From a7670d425b75f9e44b7d4d0aea04f4a6d5f34291 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Wed, 19 Jul 2017 17:24:31 -0700 Subject: [PATCH] driver core: make device_{add|remove}_groups() public Many drivers create additional driver-specific device attributes when binding to the device. To avoid them calling SYSFS API directly, let's export these helpers.
