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. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
