+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.
