Subject: ASoC: rt700: Fix return check for devm_regmap_init_sdw()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=db1a4250aef53775ec0094b81454213319cc8c74;p=linux.git

ASoC: rt700: Fix return check for devm_regmap_init_sdw()

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.
