Subject[PATCH 5.8 040/118] ASoC: rt1308-sdw: Fix return check for devm_regmap_init_sdw()
Date
From: Vinod Koul <vkoul@kernel.org>

[ Upstream commit 344850d93c098e1b17e6f89d5e436893e9762ef3 ]

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>
