1532a07042 [media] v4l: Remove hardcoded module names passed to v4l2_i2c_new_subdev*
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.

8298f2f810 [media] Support for Elgato Video Capture
This patch allows this device successfully to show video, at least from
its composite input.

I have no information about the true hardware contents of this device and so
this patch is based solely on fiddling with things until it worked. The
chip appears to be em2860, and the closest device with equivalent inputs
is the Typhoon DVD Maker. Copying the settings for that device appears
to do the trick. That's what this patch does.

d5906dd656 V4L/DVB: em28xx: the default std was not passed on to the subdevs
The initial em28xx std (PAL) was not passed on to the subdevs. This led to
these tvp5150 kernel log errors when running v4l2-ctl --all:

tvp5150 0-005c: VBI can't be configured without knowing number of lines

The reason was that tvp5150 was still using its own internal default: STD_ALL.

This patch address an arithmetic error for the case where the only remaining

where that happened to be at the end of the frame, we would inject it into the

c373cabfbb V4L/DVB: em28xx: fix a regression caused by the rc-map changes
The patch that adds the rc-map changes didn't take into account that an
a table with IR_TYPE_UNKNOWN would make change_protocol to return -EINVAL.

As this function is fundamental to initialize some data, including a
callback to the getkey function, this caused the driver to stop working,
hanging the machine most of the times.

The fix were simply to add a handler for the IR type, but, to avoid further
issues, explicitly call change_protocol and handle the error before
initializing the IR. Also, let input_dev to start/stop IR handling,
after the opening of the input device.

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking 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.

To be done: it seems that with the proposed patch the digital demodulator

Workaround is to unplug and replug the device when switching from digital to
analogue. If someone can explain how to verify the gpio settings using the
usbsnoop, the above issue perhaps can be resolved.

19f48cb105 V4L/DVB (13961): em28xx-dvb: fix memleak in dvb_fini()
this patch fixes a memory leak which occurs when an em28xx card with DVB
extension is unplugged or its DVB extension driver is unloaded. In
dvb_fini(), dev->dvb must be freed before being set to NULL, as is done
in dvb_init() in case of error.
Note that this bug is also present in the latest stable kernel release.

Make the VBI support work for PAL standards in addition to NTSC.

This work was sponsored by EyeMagnet Limited.

Thanks go out to Andy Walls for providing a CD containing test PAL/VBI captures
and to Steven Toth for providing a PVR-350 to do signal generation with.

971e8298de V4L/DVB (13680): ir: use unsigned long instead of enum
When preparing the linux-next patches, I got those errors:

include/media/ir-core.h:29: warning: left shift count >= width of type
In file included from include/media/ir-common.h:29,
                 from drivers/media/video/ir-kbd-i2c.c:50:
drivers/media/video/ir-kbd-i2c.c: In function ‘ir_probe’:
drivers/media/video/ir-kbd-i2c.c:324: warning: left shift count >= width of type

Unfortunately, enum is 32 bits on i386. As we define IR_TYPE_OTHER as 1<<63,
it won't work on non 64 bits arch.

579e7d60ba V4L/DVB (13617): ir: move input_register_device() to happen inside ir_input_register()
We'll need to register a sysfs class for the IR devices. As such, the better
is to have the input_register_device()/input_unregister_device() inside
the ir register/unregister functions.

Also, solves a naming problem with V4L ir_input_init() function, that were,
in fact, registering a device.

While here, do a few cleanups at budget-ci IR logic.

b779974bdf V4L/DVB (13575): em28xx: Use the complete address/command RC5 code for WinTV USB2
This device uses an i2c chip to retrieve the keycode from a RC5 remote.
Instead of just getting 6 bits, improve the routine to get 11 bits.

This means that the complete RC5 table for Hauppauge Grey IR can be used
with this device.

Unfortunately, it seems that this IR receiver is not capable of getting
the full 14 (or 13 bits) from the RC5 protocol.

At lest now, with the new code, it is possible to replace this IR table
by another RC5 table.
