V4L/DVB: cx22702: Simplify cx22702_set_tps()
Code in function cx22702_set_tps() can be slightly simplified.
Apparently gcc was smart enough to optimize it anyway, but it can't
hurt to make the code more readable.

The tda8425 initialization function sets up the inputmap for riva boards.
After some digging I discovered that this was for the V4L rivatv driver
that is found on sourceforge. This driver hasn't been maintained since the
last 5 years and will no longer work with the current v4l framework.
So we can safely remove this.

V4L/DVB: imon: split mouse events to a separate input dev
This is a stab at separating the mouse (and front panel/knob) events
out to a separate input device. This is necessary in preparation for
the next patch which makes the rc-core input dev opaque to rc
drivers.
I can't verify the correctness of the patch beyond the fact that it
compiles without warnings. The driver has resisted most of my
attempts at understanding it properly...for example, the double calls
to le64_to_cpu() and be64_to_cpu() which are applied in
imon_incoming_packet() and imon_panel_key_lookup() would amount
to a bswab64() call, irregardless of the cpu endianness, and I think
the code wouldn't have worked on a big-endian machine...
- Minor alterations to apply with minimal core IR changes
- Use timer for imon keys too, since its entirely possible for the
receiver to miss release codes (either by way of another key being
pressed while the first is held or by the remote pointing away from
the recevier when the key is release. yes, I know, its ugly).
- Bump driver version number, since this is a fairly significant change
(for the much much better).
Tested successfully w/an imon knob receiver.

V4L/DVB: IR: export ir_keyup so imon driver can use it directly
The imon driver currently reimplements its own version of ir_keyup
(along with key release timer functionality also already present in the
core IR code). A follow-up imon patch will make use of ir_keyup and the
IR stack's key release code.
Trivial extraction from David Härdeman's pending rc-core merge and
device interface abstraction patchset to facilitate merging a patch
based on his imon input dev split patch ahead of the larger churn, which
is slated for post-2.6.37-rc1 (after Dmitry's large keycode patches are
merged in mainline).

The only reason for keeping I2C_HW_SAA7134 is to allow setting a
per-device polling interval. Just move this info to the platform
data, allowing drivers to change it per device, where needed.

V4L/DVB: usbvision: remove BKL from usbvision
Removed the BKL from usbvision.
There was an initialization bug as well where the i2c bus was registered twice.
Although when the BKL was present no oops was generated, I did run into
other i2c problems. Now that I protect against duplicate i2c registration
that bug is now gone as well.
But trying to disconnect the USB cable while someone is still using the device
still leads to a crash.

The include/media/v4l2-i2c-drv.h header was used to be able to compile drivers
in the v4l-dvb hg repository for legacy kernels (mainly pre-2.6.26) without
creating an #ifdef mess.
The hg repository dropped support for kernels < 2.6.26 so we can remove this
header. All i2c drivers that used it have now been converted to use proper
i2c code. The header was a hack, but it did its job well. So I would call
this an honorable removal. :-)

V4L/DVB: videotext: remove this obsolete API
Remove the vtx (aka videotext aka teletext) API from the v4l2 core.
This API was scheduled for removal in kernel 2.6.35.
The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.
In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.
The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.
