From 55314e9ff8225d0c110e6598d2837baac17a30cd Mon Sep 17 00:00:00 2001

Subject: [PATCH] Input: edt-ft54x6: Clean up timer and workqueue on
remove
If no interrupt is defined then a timer and workqueue are used
to poll the controller.
On remove these were not being cleaned up correctly.
Fixes: ca61fdaba79f "Input: edt-ft5x06: Poll the device if no interrupt is
configured."
