Subject: [PATCH] ASoC: rt715: Fix return check for devm_regmap_init_sdw()
Git-commit: 282eb0b52e3f0399ee48a4cad0d9ffec840b0164
Patch-mainline: v5.9-rc6
References: jsc#SLE-16518
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.
