[PATCH 05/22] Input: ad7877 - use device core to create driver-specific device attributes

From: Dmitry Torokhov
Date: Fri Jul 28 2023 - 20:53:21 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.
