IMO, the enclosed patch should do a better job with repeat events, without
needing to change rc-core/input/event logic.

Subject: Use a more consistent value for RC repeat period
From: Mauro Carvalho Chehab <mche...@redhat.com>
The default REP_PERIOD is 33 ms. This doesn't make sense for IR's,
as, in general, an IR repeat scancode is provided at every 110/115ms,
depending on the RC protocol. So, increase its default, to do a
better job avoiding ghost repeat events.
