This patch, which basically reverts

on-boot or on-capture hang on the XO-1 laptop.
It seems like the cafe hardware is flakier than we thought and that in
some cases, the commands get executed but are never reported as completed

Reintroduce the 1-second CAFE_SMBUS_TIMEOUT to catch and avoid this

[media] go7007: MJPEG buffer overflow
The go7007 driver has a potential buffer overflow and pointer corruption
bug which causes a crash while capturing MJPEG. The motion detection
(MODET) active_map array can be overflowed by JPEG frame data that
emulates a MODET start code. The active_map overflow overwrites the
active_buf pointer, causing a crash.
The JPEG data that emulated MODET start code was being removed from the
output, resulting in garbled JPEG frames. Therefore ignore MODET start
codes when MODET is not enabled.

V4L/DVB: Deprecate stradis driver
The driver author seems to not worked on this driver since its conversion
from 2.2 to 2.4. Nobody is known to have a stradis hardware for testing. As
it still uses V4L1 API, BKL and probably some other old stuff, someone would
need to work on it to preserve the driver. Instead of investing time and
efforts to keep porting it to work with new API's, it seems better to just
drop the driver.
So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody
cares enough to port parallel port support to gspca or to create a new driver
that uses the same gspca-cpia sub-driver.

2) it doesn't seem important to keep support for a parallel port webcam,

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.
