4.14-stable review patch.  If anyone has any objections, please let me know.

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

[ Upstream commit a342083abe576db43594a32d458a61fa81f7cb32 ]

We should be using flush_delayed_work() instead of flush_work() in
matrix_keypad_stop() to ensure that we are not missing work that is
scheduled but not yet put in the workqueue (i.e. its delay timer has not
expired yet).
