Subject: [PATCH] media: rc: mce_kbd decoder: fix stuck keys
backport of https://patchwork.linuxtv.org/patch/48519/
The MCE Remote sends a 0 scancode when keys are released. If this is not
received or decoded, then keys can get "stuck"; the keyup event is not
sent since the input_sync() is missing from the timeout handler.
