[media] redrat3: new rc-core IR transceiver device driver
This is a new rc-core device driver for the IR transceivers made by
RedRat Ltd. (http://redrat.co.uk/). It started out life as an
out-of-lirc-tree lirc driver, maintained in its own repo on sourceforge,
by Stephen Cox. He started porting it to what was then ir-core, and I
finally picked it up about two week ago and did a fairly large overhaul
on it, and its now into a state where I'm fairly comfortable submitting
it here for review and inclusion in the kernel. I'm claiming authorship
of this driver, since while it started out as Stephen's work, its
definitely a derivative work now, at 876 lines added and 1698 lines
removed since grabbing it from sourceforge. Stephen's name is retained
as secondary author though, and credited in the headers. Those
interested in seeing how the changes evolved can (at least for now) look
at this branch in my git tree:
http://git.kernel.org/?p=linux/kernel/git/jarod/linux-2.6-ir.git;a=shortlog;h=refs/heads/redrat3
That won't be around forever though, and I'm doing this as a single
commit to go into mainline. Anyway...
I've successfully tested in-kernel decode of rc5, rc6 and nec remotes,
as well as lirc userspace decode of rc5 and rc6. There are still some
quirks here to sort out with rc5 lirc userspace decode, but I'm working
with the RedRat folks themselves to figure out what's going on there
(rc5 lirc decode works, but you only get an event on key release --
in-kernel rc5 decode behaves perfectly fine). Note that lirc decode of
rc6 is working perfectly. Transmit is also working, tested by pointing
the redrat3 at an mceusb transceiver, which happily picked up the
transmitted signals and properly decoded them.
There's no default remote for this hardware, so its somewhat arbitrarily
set to use the Hauppauge RC5 keymap by default. Easily changed out by
way of ir-keytable and irrelevant if you're using lircd for decode.

[media] V4L: mt9m111: fix pixel clock
This camera driver supports only rising edge, which is the default
setting of the device. The function mt9m111_setup_pixfmt() overwrites
this setting. So the driver actually uses falling edge.
This patch corrects that.

resulting in capture sometimes being offset by 1/3rd of a picture.
* There were a lot of variables duplicating information the driver
already knew, which have been removed.
* There was an in-kernel format conversion - libv4l can do this one,
and is the right place to do format conversions anyway.

[media] media: fsl_viu: fix bug in streamon routine
Currently video capturing using streaming I/O method
doesn't work if capturing to overlay buffer took place
before.
When enabling the stream we have to check the overlay
enable driver flag and reset it so that the interrupt
handler won't execute the overlay interrupt path after
enabling DMA in streamon routine. Otherwise the capture
interrupt won't be handled correctly causing non working
VIDIOC_DQBUF ioctl.

usb_altnum_to_altsetting() may return NULL. If it does we'll dereference a
NULL pointer in
drivers/media/video/gspca/stv06xx/stv06xx_pb0100.c::pb0100_start().
As far as I can tell there's not really anything more sensible than
-ENODEV that we can return in that situation, but I'm not at all intimate
with this code so I'd like a bit of review/comments on this before it's
applied.
Anyway, here's a proposed patch.

It should not be possible to enter mpeg_open and acquire core->lock
without the blackbird driver being registered, so just error out if it
is not. This makes the code more readable and should prevent the bug
fixed by the patch "hold device lock during sub-driver initialization"
from resurfacing again.
Similarly, if we enter mpeg_release and acquire core->lock then either
the blackbird driver is registered (since open files keep it loaded)
or the sysadmin forced the driver's removal. In the latter case the
state will be inconsistent and this is worth a loud warning.
