From: Sean Young sean@mess.org Date: Sun, 1 Oct 2017 16:38:29 -0400 Subject: media: rc: nec decoder should not send both repeat and keycode
From: Sean Young sean@mess.org
commit 829bbf268894d0866bb9dd2b1e430cfa5c5f0779 upstream.
When receiving an nec repeat, rc_repeat() is called and then rc_keydown() with the last decoded scancode. That last call is redundant.
Fixes: 265a2988d202 ("media: rc-core: consistent use of rc_repeat()")
