Subject: [PATCH 13/22] Input: ili210x - use device core to create driver-specific device attributes
Date:   Fri, 28 Jul 2023 17:51:22 -0700
Message-ID: <20230729005133.1095051-13-dmitry.torokhov@gmail.com>

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.
