Subject: [PATCH v2 5/5] ASoC: rt700: Fix return check for devm_regmap_init_sdw()
Date: Wed, 26 Aug 2020 22:03:40 +0530 [thread overview]
Message-ID: <20200826163340.3249608-6-vkoul@kernel.org> (raw)
In-Reply-To: <20200826163340.3249608-1-vkoul@kernel.org>
devm_regmap_init_sdw() returns a valid pointer on success or ERR_PTR on
failure which should be checked with IS_ERR. Also use PTR_ERR for
returning error codes.
Reported-by: Takashi Iwai <tiwai@suse.de>
Fixes: 7d2a5f9ae41e ("ASoC: rt700: add rt700 codec driver")
