[PATCH 5.8 042/118] ASoC: rt715: Fix return check for devm_regmap_init_sdw()

From: Greg Kroah-Hartman
Date: Mon Sep 21 2020 - 12:57:05 EST


From: Vinod Koul <vkoul@xxxxxxxxxx>

[ Upstream commit 282eb0b52e3f0399ee48a4cad0d9ffec840b0164 ]

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.
