   4 Subject: [PATCH] Input: edt-ft54x6: Clean up timer and workqueue on
   5  remove
   6
   7 If no interrupt is defined then a timer and workqueue are used
   8 to poll the controller.
   9 On remove these were not being cleaned up correctly.

  11 Fixes: ca61fdaba79f "Input: edt-ft5x06: Poll the device if no interrupt is
  12 configured."
