Fixed up trivial conflict in drivers/media/video/bt8xx/bttv-input.c
as per Tejun.
I found that the problems people have reported with the USB-TV-stick
"Terratec Cinergy Hybrid T USB XS" (USB-ID: 0ccd:0042)
are coming from a wrong header file in the v4l-sources.
Attached is a diff, which fixes the problem (tested successfully here).
Obviously the USB-ID has been associated with a wrong chip: EM2880
instead of EM2882, which would be correct.

Video drivers request submodules using a work during probe and calls
flush_scheduled_work() on exit to make sure the work is complete
before being unloaded. This patch makes these drivers flush the work
directly instead of using flush_scheduled_work().
While at it, relocate request_submodules() call in saa7134_initdev()
right right before successful return as in other drivers to avoid
failing after the work is scheduled and returning failure without the
work still active.
This is in preparation for the deprecation of flush_scheduled_work().

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.

This adds support for the KWorld PlusTV 340U and KWorld UB345-Q ATSC
sticks, which are really the same device. The sticks have an eMPIA
em2870 usb bridge chipset, an LG Electronics LGDT3304 ATSC/QAM
demodulator and an NXP TDA18271HD tuner -- early versions of the 340U
have a a TDA18271HD/C1, later models and the UB435-Q have a C2.

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.

Adds digital and analogue tv support for Dikom DK300 hybrid usb card.
Not working: remote controller
To be done: it seems that with the proposed patch the digital demodulator
remains activated if the tuner is switched from digital to analogue mode.
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.

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.

Modifies the IR table for HVR-950 to use the newer Hauppauge RC5 table,
and adds the RC5 address to the functions that get the scancode for this
device.
It is easy to add support for all other RC5 IR's on em2880 boards, but
the scancode table needs to be re-generated. So, keep using the old
7bits tables while we don't have all tables converted.
Also, the 7bits tables are still used on other drivers, so this small
patch needs to be ported to all drivers.

Upcoming I2C v4l2_subdev drivers need a way to control the subdevice
power state from the core. This use case is already partially covered by
the tuner s_standby operation, but no way to explicitly come back from
the standby state is available.
Rename the tuner s_standby operation to core s_power, and fix tuner
drivers accordingly. The tuner core will call s_power(0) instead of
s_standby(). No explicit call to s_power(1) is required for tuners as
they are supposed to wake up from standby automatically.

Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:
1) It requires that the scancode to be at the range 00-7f;
2) keycodes should be masked on 7 bits in order for it to work;
3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;
4) it is different than what is done with dvb-usb approach;
5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.
This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
u16 scancode;
u32 keycode;
};
This is very close to what dvb does. So, a further integration with DVB
code will be easy.
While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.
The only notable effect is the redution of about 35% of the ir-common
module size:
text data bss dec hex filename
6721 29208 4 35933 8c5d old/ir-common.ko
5756 18040 4 23800 5cf8 new/ir-common.ko
In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.
This patch itself shouldn't be doing any functional changes.
