[media] tda9840: fix setting of the audio mode

2012-05-14T17:57:02+00:00

You have to first detect the current rxsubchans (mono, stereo or bilingual), and depending on that you can set the audio mode. It does not automatically switch when the audio channels change. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] convert drivers/media/* to use module_i2c_driver()

2012-03-08T11:48:01+00:00

This patch converts the drivers in drivers/media/* to use the module_i2_driver() macro which makes the code smaller and a bit simpler.

[media] v4l: make sure drivers supply a zeroed struct v4l2_subdev

2011-04-29T15:33:28+00:00

Some v4l drivers currently don't initialize their struct v4l2_subdev with zeros, and this is a problem since some of the v4l2 code expects this. One example is the addition of internal_ops in commit 45f6f84, after that we are at risk of random oopses with these drivers when code in v4l2_device_register_subdev tries to dereference sd->internal_ops->*, as can be shown by the report at http://bugs.launchpad.net/bugs/745213 and analysis of its crash at https://lkml.org/lkml/2011/4/1/168 Use kzalloc within problematic drivers to ensure we have a zeroed struct v4l2_subdev.

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.

V4L/DVB (11372): v4l2: use old-style i2c API for kernels < 2.6.26 instead of < 2.6.22

2009-04-07T00:44:23+00:00

Originally the intention was to switch to the new style i2c API starting with the introduction of the API in 2.6.22. However, the i2c_new_probed_device() function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately, it was only fixed in the stable series of 2.6.25 and 2.6.26. Given the fact that the new i2c API also changed starting with 2.6.26 (the addition of i2c_device_id), it is easiest to switch APIs starting with 2.6.26. This patch updates all the legacy code accordingly. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (10499): saa7146: convert saa7146 and mxb in particular to v4l2_subdev.

2009-03-30T15:42:42+00:00

Modified mxb to load the i2c modules through v4l2_subdev. So no more probing. Modified tea6415c and tea6420 to use the standard routing ops to do the routing, rather than using private commands. Dropped the private commands from tda9840 (they were never used except during initialization of the module). Added saa7146 support for VIDIOC_DBG_G_CHIP_IDENT. Converted saa5246a and saa5249 to v4l2_subdev. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl.

2009-01-02T19:11:34+00:00

Since internal to v4l2 the ioctl prototype is the same regardless of it being called through .ioctl or .unlocked_ioctl, we need to convert it all to the long return type of unlocked_ioctl. Thanks to Jean-Francois Moine for posting an initial patch for this and thus bringing it to our attention. Cc: Jean-Francois Moine Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
