From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> [ Upstream commit a94eaccefea1186947c5c5451fcae2245dd7e714 ] kmemleak throws error reports on module load/unload tests, add snd_hdac_regmap_exit() in .remove(). While we are at it, also fix the error handling flow in .probe() to use snd_hdac_regmap_exit() if needed.
