Subject: V4L/DVB: IR/imon: add proper auto-repeat support
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=db190fc13af8e2e5e9d717c16b07342ea8bf9174;p=linux-beck.git

V4L/DVB: IR/imon: add proper auto-repeat support

Simplified from version 1, in that hacks heisted from ati_remote2.c
aren't actually necessary, the real fix for too many repeats was
from setting too long a timer release value (200ms) on repeats in
mce mode -- this patch drops the release timeout to 33ms, matching
the input subsystem default input_dev->rep[REP_PERIOD].
