Subject: [PATCH 491/828] 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."
