[PATCH 01/22] Input: cros_ec_keyb - use device core to create driver-specific device attributes

From: Dmitry Torokhov
Date: Fri Jul 28 2023 - 20:55:25 EST


Instead of creating driver-specific device attributes with
devm_device_add_group() have device core do this by setting up dev_groups
pointer in the driver structure.
