V4L/DVB (13540): ir-common: Cleanup get key evdev code
The same loop to seek for a key were used on different places. Also, no spinlock were protecting it to avoid the risk of replacing a keycode while seeking for a new code. This cleanup does: - create an unique function to seek for a code; - adds an spinlock to protect the table lookup; - remove some unused code; - simplifies to code to make it easier to understand. Basically no change in behavior should be noticed after this patch. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
