There are several places pointing to old documentation files:
Documentation/video4linux/API.html
Documentation/video4linux/bttv/
Documentation/video4linux/cx2341x/fw-encoder-api.txt
Documentation/video4linux/m5602.txt
Documentation/video4linux/v4l2-framework.txt
Documentation/video4linux/videobuf
Documentation/video4linux/Zoran
Make them point to the new location where available, removing
otherwise.

As we move stuff around, some doc references are broken. Fix some of
them via this script:
./scripts/documentation-file-ref-check --fix
Manually checked if the produced result is valid, removing a few
false-positives.

The vzalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:
vzalloc(a * b)
with:
vzalloc(array_size(a, b))
as well as handling cases of:
vzalloc(a * b * c)
with:
vzalloc(array3_size(a, b, c))
This does, however, attempt to ignore constant size factors like:
vzalloc(4 * 1024)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:
kmalloc(a * b, gfp)
with:
kmalloc_array(a * b, gfp)
as well as handling cases of:
kmalloc(a * b * c, gfp)
with:
kmalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kmalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kmalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().
The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- remove of atomisp driver from staging, as nobody would have time to
dedicate huge efforts to fix all the problems there. Also, we have a
feeling that the driver may not even run the way it is.
- move Zoran driver to staging, in order to be either fixed to use VB2
and the proper media kAPIs or to be removed
- remove videobuf-dvb driver, with is unused for a while
- some V4L2 documentation fixes/improvements
- new sensor drivers: imx258 and ov7251
- a new driver was added to allow using I2C transparent drivers
- several improvements at the ddbridge driver
- several improvements at the ISDB pt1 driver, making it more coherent
with the DVB framework
- added a new platform driver for MIPI CSI-2 RX: cadence
- now, all media drivers can be compiled on x86 with COMPILE_TEST
- almost all media drivers now build on non-x86 architectures with
COMPILE_TEST
- lots of other random stuff: cleanups, support for new board models,
bug fixes, etc

CineS2 V7(A) and Octopus CI S2 Pro/Advanced cards support faster TS speeds
on the card's contained stv0910 demodulator when their FPGA was updated
with a recent (>= 1.7, version number applies to all mentioned cards)
vendor firmware. Enable this faster TS speed on card port 0 (contained
demod) and parallel stv0910 connections when the card firmware is at least
1.7 or later.
Note: The mentioned cards and their demods are handled via the STV0910_PR
and STV0910_P tuner types. DuoFlex modules with such demodulators are
handled via the STV0910 (without suffix) types where such TS speed
increase doesn't technically make sense.

Add a tsspeed config option to struct stv0910_cfg which can be used by
users of the driver to set the (parallel) TS speed (higher speeds enable
support for higher bitrate transponders). If tsspeed isn't set in the
config, it'll default to a sane value.
This commit also updates the two consumers of the stv0910 driver (ngene
and ddbridge) to have a default tsspeed in their stv0910_cfg templates.

Fixes two checkpatch warnings
WARNING: function definition argument 'xxx' should also have an identifier name
in the ddb_mci_attach() prototype definition. checkpatch keeps complaining
on the "int (**fn_set_input)" as it seems to have issues with the
ptr-to-ptr, though this probably needs fixing in checkpatch.

In stop(), an (unlikely) out-of-bounds write error can occur when setting
the demod_in_use element indexed by state->demod to zero, as state->demod
isn't checked for being in the range of the array size of demod_in_use, and
state->demod maybe carrying the magic 0xff (demod unused) value. Prevent
this by checking state->demod not exceeding the array size before setting
the element value. To make the code a bit easier to read, replace the magic
value and the number of array elements with defines, and use them at a few
more places.
Detected by CoverityScan, CID#1468550 ("Out-of-bounds write")
Thanks to Colin for reporting the problem and providing an initial patch.

When the driver is configured in the "memcpy" dma-mode,
it uses vb2_vmalloc_memops, which is backed by a SLAB
allocator and so shouldn't be using GFP_DMA32.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.
Note:
- The various VIDEOBUF*DMA* symbols had to loose their dependencies on
HAS_DMA, as they are selected by several individual drivers.

This driver hasn't been tested in a long, long time. The hardware is
ancient and pretty much obsolete. This driver also needs to be converted
to newer media frameworks (vb2!) but due to the lack of time and interest
that is unlikely to happen.
So this driver is a prime candidate for removal. If someone is interested
in working on this driver to prevent its removal, then please contact the
linux-media mailinglist.

This bug affects all of Hauppauge QuadHD boards when used on all Ryzen
platforms and some XEON platforms. On these platforms it is possible to
error out the RiSC engine and cause it to stall, whereafter the only
way to reset the board to a working state is to reboot.
This is the fatal condition with current driver:

of board initialization, reset, DMA start, and DMA stop. If both registers

On Ryzen systems interrupts are occasionally missed:
cx23885: cx23885_wakeup: [ffff99b384b83c00/28] wakeup reg=5406 buf=5405
cx23885: cx23885_wakeup: [ffff99b40bf79400/31] wakeup reg=9537 buf=9536
This patch loops up to five times on wakeup, marking any buffers
found done.
Since the count register is u16, but the vb2 counter is u32, some modulo
arithmetic is used to accommodate wraparound and ensure current active
buffer is the buffer expected.

In commit 20a63349b142 a new variable ktime_t delay has been added.
We decided to use the API functions to initialize ktime_t variables
within media-tree. Thus variable delay needs to be initialized with
ktime_set() instead of setting it directly.

This issue was reported by a user who downloaded a corrupt saa7164
firmware, then went looking for a valid xc5000 firmware to fix the
error displayed...but the device in question has no xc5000, thus after
much effort, the wild goose chase eventually led to a support call.
The xc5000 has nothing to do with saa7164 (as far as I can tell),
so replace the string with saa7164 as well as give a meaningful
hint on the firmware mismatch.

Replace the manual validity checks for the GPIO with the
gpio_is_valid().
In vip_gpio_reserve(), Error checking for gpio pin is not correct.
If pwr_pin = -1, It will return 0. This should be return an error.
In sta2x11_vip_init_one(), Error checking for gpio 'reset_pin'
is unnecessary. Because vip_gpio_reserve() is also checking for
valid gpio pin. So removed extra error checking for gpio 'reset_pin'.

Interrupt behavior shows that some time the frame end and frame start of
next frame is unstable and can range from several to hundreds of
micro-sec. In the case of ~10us, isr may not clear next sof interrupt
status in single handling, which prevents new interrupts from coming.
Fix this by handling all pending IRQs before exiting isr, so any abnormal
behavior results from very short interrupt status changes is protected.

getting invoked both in buffer_queue and start_streaming, which
was intermittently causing invalid opcodes on the VBI RISC queue.
This change effectively mirrors the exact same change Hans Verkuil

Commit ee93340e98bc ("media: ngene: deduplicate I2C adapter evaluation")
added a helper to evaluate the I2C adapter to be used for demod/tuner
attachment based on the given ngene_channel, and that helper is used in
many attach functions to initialise the i2c_adapter variable. However,
for some reason in tuner_attach_stv6110() and demod_attach_stv0900(), the
adapter evaluation wasn't removed as in all other functions. Fix (or
finalize, even) the helper use by cleaning up the superfluous I2C adapter
evaluation leftover in these two functions.

This adds initial support for the new MCI-based (micro-code interface)
DD cards, with the first one being the MaxSX8 eight-tuner DVB-S/S2/S2X
PCIe card. The MCI is basically a generalized interface implemented in
the card's FPGA firmware and usable for all kind of cards, without the
need to implement any demod/tuner drivers as this interface "hides" any
I2C interface to the actual ICs, in other words any required driver is
implemented in the card firmware.
At this stage, the MCI interface is quite rudimentary with things like
signal statistics reporting missing, but is already working to serve
DVB streams to DVB applications. Missing functionality will be enabled
over time.
This implements only the ddbridge-mci sub-object and hooks it up to the
Makefile so the object gets build. The upcoming commits hook this module
into all other ddbridge parts where required, including device IDs etc.

The Octopus V3 and Octopus Mini devices support set up of a dummy tuner
mode on port 0 that will deliver a continuous data stream of 125MBytes
per second while raising IRQs and filling the DMA buffers, which comes
handy for some stress, PCIe link and IRQ handling testing. The dummy
frontend is registered using dvb_dummy_fe's QAM dummy frontend. Set
ddbridge.dummy_tuner to 1 to enable this on the supported cards.
