From 829bbf268894d0866bb9dd2b1e430cfa5c5f0779 Mon Sep 17 00:00:00 2001 From: Sean Young Date: Sun, 1 Oct 2017 16:38:29 -0400 Subject: [PATCH] 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.
