4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sean Young <sean@xxxxxxxx>
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()")
