Subject: [PATCH 16/22] Input: melfas-mip4 - use device core to create driver-specific device attributes
Date:   Fri, 28 Jul 2023 17:51:25 -0700

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.
