From e323b2dddc1ce7ea7f032c986c012a04d5977dc8 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 19 Jul 2017 17:24:32 -0700 Subject: driver core: add device_{add|remove}_group() helpers We have helpers that work with NULL terminated array of groups, but many drivers only create a single supplemental group, and do not want to declare a group array. Let's provide them with helpers working with a single group.
