From e91422dd68f18e3d8f90bbb81993d11ee223fe9b Mon Sep 17 00:00:00 2001 From: Ben Zhang Date: Wed, 19 May 2021 15:22:17 -0400 Subject: drivers/gpio_keys: Add label to set input device name Added the label field to the gpio_keys _DSD so that the kernel driver can use a meaningful name instead of the generic _HID PRP0001. BUG=b:184593945 BRANCH=puff TEST=build image and verify with evtest on puff: /dev/input/event3: mic_mute_switch UI event_device_info receives the proper name.
