From 3184125ee2da70c5189cdf03c86cfeac7dd7bba9 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 19 Jul 2017 17:24:34 -0700 Subject: [PATCH] Input: gpio_keys - use devm_device_add_group() for attributes Now that we have proper managed API to create device attributes, let's start using it instead of the manual unwinding.
