From 8edcd98be1b237965b54bee7e17f89a790a107fd Mon Sep 17 00:00:00 2001 From: Fuqian Huang Date: Sat, 13 Jul 2019 01:04:12 -0700 Subject: Input: cyapa - switch to using devm_add_action_or_reset() devm_add_action_or_reset() is introduced as a helper function which internally calls devm_add_action(). If devm_add_action() fails then it will execute the action mentioned and return the error code. This reduce source code size (avoid writing the action twice) and reduce the likelyhood of bugs.
