Subject: [PATCH 4.14 023/183] Input: ps2-gpio - flush TX work when closing port

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

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

[ Upstream commit 33a841ce5cef4ca6c18ad333248b6d273f54c839 ]

To ensure that TX work is not running after serio port has been torn down,
let's flush it when closing the port.
