755a18baad V4L/DVB (7851): Fix FW_LOADER depencency at v4l/dvb
Since:
1) FW_LOADER is defined as:

config FW_LOADER
        tristate "Userspace firmware loading support"
        depends on HOTPLUG

2) several V4L/DVB driver just selects it;

3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.

So, All drivers that select FW_LOADER should also depend on HOTPLUG.

An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:

drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD
-> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA ->
USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB

eabcaf3204 V4L/DVB (7848): Fix dependencies for tuner-xc2028 and em28xx-dvb
em28xx-dvb doesn't need FW_LOADER. Instead, tuner-xc2028 needs to select
FW_LOADER.

Also, this can happen only if HOTPLUG is selected, since FW_LOADER
is dependent on HOTPLUG.

 http://redhat.com/~mingo/misc/config-Wed_Apr_30_10_21_40_CEST_2008.bad

the problem is caused by the drivers/media/common/tuners/ subdirectory

The patch extends the default keymap of FlyVIdeo2000 IR remote control so that

I bought a SAA7130 TV tuner with a remote control having 3 additional button
as the default layout, exactly as:

1) labeled "<<<" : key code 0x19, may be used as "backward"in MPlayer,XMMS etc

2) labeled ">>>" : key code 0x1f, may be used as "forward"...

3) not labeled : key code 0x0a, may be used as "pause"...

Once have added these code definitions to the kernel, me got all these
operations available for viewing movies & listening music.

057596eea8 V4L/DVB (7133): Fix Kconfig dependencies
As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes.

This patch moves the functions that videodev needs from v4l2-common. It also
fixes some Kconfig changes.

After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked
into kernel. v4l2-common will be m, and all V4L drivers will also be m.

This approach is very conservative, since it is possible to have V4L drivers
that don't need I2C or v4l2-common. The better is to map what drivers really
need v4l2-common, making them to select v4l2-common, and allowing the others to
be 'y', 'm' and 'n'.

Video_device_alloc returns the result of a kzalloc.  In this case, the
value is stored in a local variable which is not copied elsewhere before

This change adds support for 4 extra keys on the remote currently being

The extra keys are at the bottom and are labeled MCE +VOL, -VOL, +CH, -CH.
I chose to map them to the F21-F24 keycodes, following the precedent of
ir_codes_gotview7135[], so as to differentiate these 'MCE' keys from the
other +VOL, -VOL, +CH, -CH 'arrow' keys higher up on the remote.

8ae1fe2a09 V4L/DVB (6508): ttpci: Rework Kconfig menus and Makefile
The ttpci Kconfig file has bugs that cause it to fail in certain Kconfig
situations.  The basic problem is that it selects certain drivers, but does
not depend on the dependencies of those drivers.

See http://article.gmane.org/gmane.comp.video.video4linux/35072

Using the Kconfig file also has some annoyances.  For instance one can't turn
off AV7110 support unless you go down several options and first turn off
budget-patch support.  Normally user selectable drivers are not forced on like
this.

The "AV7110 cards with Budget Patch" option is disabled if "Budget cards"
isn't on.  Normally a driver appears nested under a driver it depends on, but
since drivers that don't depend on "Budget cards" are between the two options,
the config programs can't display the tree correctly.

The Makefile has an issue too.  Some modules, ttpci-eeprom and budget-core,
appear in the Makefile under several different config symbols.  If more than
one of these symbols is on, they will get added the to list of objects
multiple times.  The normal convention is to have a config symbol just the
common object(s) and have the users of the that object either depend on or
select that config symbol.

This patch fixes all these issues.  ttpci-eepom is under a new config symbol,
and so is the budget-core module.  The four different budget card types appear
as sub-drivers under a main "SAA7146 DVB cards" option.  Turning on
budget-patch doesn't force AV7110.  Drivers using SAA7146_VV have the
necessary VIDEO_DEV dependency, so that it isn't possible to select SAA7146_VV
without V4L being on.

19bc5133da V4L/DVB (6601): V4L: videobuf-core locking fixes and comments
- Add comments to functions that require that caller hold q->lock
- Add __videobuf_mmap_free that doesn't hold q->lock for use within videobuf
- Add locking to videobuf_mmap_free
- Fix linux/drivers/media/common/saa7146_video.c which was holding lock around
  videobuf_read_stop
- Add locking to functions that operate on a queue
- Add videobuf_stop to take care of stopping in both the read and stream case

TODO: bttv still has an unsafe call to videobuf_queue_is_busy

26ac14e24f V4L/DVB (6495): saa7146: saa7146_wait_for_debi_done fixes
Two fixes for the 'saa7146_wait_for_debi_done' code:
(a) Timeout did not work when the routine was called with
    interrupts disabled.
(b) Reduce PCI I/O load caused by saa7146_wait_for_debi_done.
    Seems to be very important on fast machines!

Based on code posted by Hartmut Birr @vdr-portal.
