* usb: storage: Convert US_DEBUGP to usb_stor_dbgJoe Perches2013-04-191-11/+12
| | | | | | | | | | | | | | | | | | | | | | | Use a more current logging style with dev_printk where possible. o Convert uses of US_DEBUGP to usb_stor_dbg o Add "struct us_data *" to usb_stor_dbg uses o usb_stor_dbg now uses struct device */dev_vprint_emit o Removed embedded function names o Coalesce formats o Remove trailing whitespace o Remove useless OOM messages o Remove useless function entry/exit logging o Convert some US_DEBUGP uses to dev_info and dev_dbg Object size is slightly reduced when debugging is enabled, slightly increased with no debugging because some initialization and removal messages are now always emitted.

* usb: Add module.h to drivers/usb consumers who really use it.Paul Gortmaker2011-10-311-0/+1
| | | | | | | | | The situation up to this point meant that module.h was pretty much everywhere, regardless of whether you asked for it or not. We are fixing that, so give the USB folks who want it an actual include of it. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* USB: Fix option_ms regression in 2.6.31-rc2Jonathan McDowell2009-07-121-0/+3
| | | | | | | | | | | | Commit 32ebbe7b6ad44ae9c276419710b56de6ba705303 which filters the SCSI REZERO command in option_ms based on a SCSI INQUIRY with a vendor of Option breaks my Option Icon 225 (0af0:6971). This device returns a vendor of ZCOPTION for the ZeroCD device. The following trivial patch fixes things for me.

* USB: usb-storage: add filter to "option_ms" to leave unrecognized devices aloneJosua Dietze2009-06-151-52/+69
| | | | | | | | | | | | | | | | | | | | | | Some unusual usb devices from the maker "Option" are switched from storage to serial/modem mode by sending a SCSI REZERO command. In one case a fairly common vendor/device ID is affected which led to problems for users of other modems or phones which are not supposed to be switched. The patch adds a filter by reading the vendor name with the SCSI INQUIRY command, and skips the switching code for all unrecognized entries. Further changes are cleanups and corrections pointed out by Alan Stern. Tested with two devices with the IDs 05c6:1000, one from "Option" and switchable, and one from Samsung (cell phone).

* USB: unusual dev for Option N.V. ZeroCD modemsDan Williams2009-01-071-0/+147
Many newer Option mobile broadband devices initially provide a usb-storage "driver CD" device that's pretty useless on Linux since any software on it most likely wouldn't be compatible with your kernel or distro anyway. Thus, by default just kill the driver CD device by sending the SCSI 'rezero' command, but allow override of the default behavior via usb-storage module parameter so users can keep the ZeroCD device if they really want to. Inspired by the Sierra TruInstall patch.
