V4L/DVB: ir-core: rename sysfs remote controller class from ir to rc
IR is an alias for Infrared Remote, while RC is an alias for Remote
Controller.
While currently all implementations are with Infrared Remote Controller,
this subsystem is not meant to be used only by IR type of RC's. So,
as discussed on both linux-media and linux-input, the better is to
rename the subsystem as Remote Controller.
While, currently, the only application that uses the /sys/class/irrcv is
ir-keytable application, and its sysfs support works only with the
current linux-next code, it is still possible to change the userspace API
without the risk of breaking applications. So, better to rename this
sooner than later.
Later patches will be needed to rename the files and to move them away
from drivers/media, but this is not a critical issue. So, for now,
let's just change the name of the sysfs class/nodes.

V4L/DVB: saa7134: don't wait too much to generate an IR event on raw_decode
At raw_decode mode, the key is processed after the end of a timer. The
previous code resets the timer every time something is received at the IR
port. While this works fine with IR's that don't implement repeat, like
Avermedia RM-JX IR, it keeps waiting until keydown, on IR's that implement
NEC repeat command, like the Terratec yellow.
The solution is to change the behaviour to do the timeout after the first
received data.
The timeout is currently set to 15 ms, as it works fine with NEC protcocol.
It may need some adjustments to support other protocols and to better handle
spurious detections that may happen with some IR sensors.

V4L/DVB: drivers/media/video: move dereference after NULL test
In quickcam_messenger.c, if the NULL test on uvd is needed, then the
dereference should be after the NULL test.
In vpif_display.c, std_info is initialized to the address of a structure
field. This seems unlikely to be NULL. Test std_info->stdid instead.
In saa7134-alsa.c, the function is only called from one place, where the
chip argument has already been dereferenced. On the other hand, if it
should be kept, then card should be initialized after it.

follows (http://coccinelle.lip6.fr/):
