From 30df385e35a48f773b85117fc490152c2395e45b Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Wed, 18 Nov 2020 22:55:39 -0800 Subject: [PATCH] Input: adp5589-keys - use devm_add_action_or_reset() for register clear The driver clears the general configuration register during the remove() hook. This should also be done in case the driver exits on error. This change move the clear of that register to the devm_add_action_or_reset() hook.
