From b4a9af9be628e4f9d09997e0bdef30f6718e88ec Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 4 Aug 2022 13:30:52 +0200 Subject: HID: playstation: convert to use dev_groups There is no need for a driver to individually add/create device groups, the driver core will do it automatically for you. Convert the hid-playstation driver to use the dev_groups pointer instead of manually calling the driver core to create the group and have it be cleaned up later on by the devm core.
