Subject[PATCH 4.17 178/220] media: rc: mce_kbd decoder: fix stuck keys
Date
4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sean Young <sean@mess.org>

commit 63039c29f7a4ce8a8bd165173840543c0098d7b0 upstream.

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.
