Subject: media: rc: partial revert of "media: rc: per-protocol repeat period" Author: Sean Young sean@mess.org Date: Sun Nov 19 16:57:27 2017 -0500
Since commit d57ea877af38 ("media: rc: per-protocol repeat period"), most IR protocols have a lower keyup timeout. This causes problems on the ite-cir, which has default IR timeout of 200ms.
Since the IR decoders read the trailing space, with a IR timeout of 200ms, the last keydown will have at least a delay of 200ms. This is more than the protocol timeout of e.g. rc-6 (which is 164ms). As a result the last IR will be interpreted as a new keydown event, and we get two keypresses.
Revert the protocol timeout to 250ms, except for cec which needs a timeout of 550ms.
Fixes: d57ea877af38 ("media: rc: per-protocol repeat period")
