[media] rename drivers/media/video as .../platform

2012-08-15T19:43:09+00:00

The remaining drivers are mostly platform drivers. Name the dir to reflect it. It makes sense to latter break it into a few other dirs. Signed-off-by: Mauro Carvalho Chehab

[media] Stop using linux/version.h on most video drivers

2011-07-27T20:53:12+00:00

All the modified drivers didn't have any version increment since Jan, 1 2011. Several of them didn't have any version increment for a long time, even having new features and important bug fixes happening. As we're now filling the QUERYCAP version with the current Kernel Release, we don't need to maintain a per-driver version control anymore. So, let's just use the default. In order to preserve the Kernel module version history, a KERNEL_VERSION() macro were added to all modified drivers, and the extraver number were incremented. I opted to preserve the per-driver version control to a few pwc, pvrusb2, s2255, s5p-fimc and sh_vou. A few drivers are still using the legacy way to handle ioctl's. So, we can't do such change on them, otherwise, they'll break. Those are: uvc, et61x251 and sn9c102. The rationale is that the per-driver version control seems to be actively maintained on those. Yet, I think that the better for them would be to just use the default version numbering, instead of doing that by themselves. While here, removed a few uneeded include linux/version.h Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l: fix handling of v4l2_input.capabilities

2010-12-30T10:02:29+00:00

The v4l core sets the v4l2_input.capabilities field based on the supplied v4l2_ioctl_ops. However, several drivers do a memset or memcpy of the v4l2_input struct, thus overwriting that field incorrectly. Either remove the memset (which is already done by the v4l core), or add the proper capabilities field in case of a memcpy. The same is also true for v4l2_output, but that only affected the ivtv driver. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l: Remove hardcoded module names passed to v4l2_i2c_new_subdev*

2010-10-22T23:50:56+00:00

With the v4l2_i2c_new_subdev* functions now supporting loading modules based on modaliases, replace the hardcoded module name passed to those functions by NULL. All corresponding I2C modules have been checked, and all of them include a module aliases table with names corresponding to what the drivers modified here use.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32+00:00

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.
