From 55314e9ff8225d0c110e6598d2837baac17a30cd Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Wed, 8 Sep 2021 14:46:17 +0100 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."
