Subject: [PATCH AUTOSEL 5.7 16/53] ASoC: hdac_hda: fix memleak with regmap not freed on remove
Date: Wed,  1 Jul 2020 21:21:25 -0400	[thread overview]
Message-ID: <20200702012202.2700645-16-sashal@kernel.org> (raw)
In-Reply-To: <20200702012202.2700645-1-sashal@kernel.org>

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ 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.
