media: rc: nec decoder should not send both repeat and keycode
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()") Cc: <stable@vger.kernel.org> # v4.14 Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
