Pull staging and IIO updates from Greg KH:
"Here is the "big" staging and IIO driver update for 4.15-rc1.
Lots and lots of little changes, almost all minor code cleanups as the
Outreachy application process happened during this development cycle.
Also happened was a lot of IIO driver activity, and the typec USB code
moving out of staging to drivers/usb (same commits are in the USB tree
on a persistent branch to not cause merge issues.)
Overall, it's a wash, I think we added a few hundred more lines than
removed, but really only a few thousand were modified at all.
All of these have been in linux-next for a while. There might be a
merge issue with Al's vfs tree in the pi433 driver (take his changes,
they are always better), and the media tree with some of the odd
atomisp cleanups (take the media tree's version)"

Shifting and masking strHostIfSetMulti->enabled is redundant since
enabled is a bool and so all the shifted and masked values will be

As part of removing the timer_list.data field, this converts the wilc1000
driver to using from_timer and an explicit per-timer data field, since
there doesn't appear to be a way to sanely resolve vif from hif_drv.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

Change the config packet format used in handle_set_wfi_drv_handler()
to align the host driver with the new format used in the wilc firmware.
The change updates the format in which the host driver provides the
firmware with the drv_handler index and also uses two new
fields viz. "mode" and 'name" in the config packet along with this index
to directly provide details about the interface and its mode to the
firmware instead of having multiple if-else statements in the host driver
to decide which interface to configure.
This change requires users to move to the newer version of the wilc
firmware(14.02 or higher) available on the vendor tree on github or on the
linux-firmware project. The existing firmware files on the linux-firmware
project are very old and best not used.

This is not the first attempt to address this problem:
https://lkml.org/lkml/2017/3/7/808
First, the current code works because the final use of the
ht_capa values (in host_interface.c: WILC_HostIf_PackStaParam) packs them
into a buffer in little-endian format. Since this matches the byte-order of
struct ieee80211_ht_cap, all is seemingly well.
What the current code does not do, and what these warnings expose, is
clearly communicate what the fields in struct add_sta_param
represent -- values with a specific (little endian) byte order.
This will lead to problems if the values are ever actually used by the
host, and that host is not little endian.
The proposed change addresses this by embedding a
struct ieee80211_ht_cap into struct add_sta_param. When the values
are later packed out, the newly embedded struct is copied directly
into the outbound buffer. All 16 and 32 bit types are treated as
little endian and marked as such. Future use of the values by the
host would still require conversion, or sparse would flag them again.
The following items are required for this to be correct:
1. The data is not currently used by the host.
2. struct ieee80211_ht_cap is packed.
3. The packing of the fields matches the order in
struct ieee80211_ht_cap.
This is similar, I believe, to how the same data is handled in
marvell/mwifiex/11n.c.
Test-compiled/loaded against staging-next on x86_64
Test-compiled against staging-next for ARM.
Applied/built against staging-testing.
Testing consists of compilation for the above trees/targets, and a
sparse check, no functional testing.

This fix removes the unnecessary call to destroy_workqueue() while opening
the device to avoid the above kernel panic. The deinit routine already
does a good job of terminating the workqueue when no longer needed.

This patch fixes the following checkpatch.pl warning: Prefer
ether_addr_copy() over memcpy() if the Ethernet addresses are
__aligned(2)
According to ether_addr_copy() description and functionality, all
Ethernet addresses should align to the u16 datatype.
Here is the output of pahole for the relevant datastructures:
struct del_sta {
u8 mac_addr[6]; /* 0 6 */
/* size: 6, cachelines: 1, members: 1 */
/* last cacheline: 6 bytes */
};

Instead of storing the return value into a variable and then returning it, we
can club the two into a single return statement. This change was made using
the following semantic patch by Coccinelle:

The patch uses the size of the dereference to a variable instead of it's type,
to make the code more resistant to type changes in the future. The type of the
pointer variable here is the same as the type in the argument that is being
replaced in sizeof().

hif_drv->usr_scan_req.net.net_info[i] contains found_net_info structs
which have the following element:
u8 bssid[6];
pstrNetworkInfo, of type network_info, also contains an u8 array named
bssid.
request->ssids is an array of cfg80211_ssid structs. Making ssid:
u8 ssid[IEEE80211_MAX_SSID_LEN];
In these 3 cases the arrays are being checked against NULL, which can't
happen. Removing the checks since they will always be true.
Found with smatch:

Deconstruct the kthread / message_queue logic, replacing it with
create_singlethread_workqueue() / queue_work() setup, by adding a
'struct work_struct' to 'struct host_if_msg'. The current kthread
hostIFthread() is converted to a work queue helper with the name
'host_if_work'.
