Subject: [PATCH -next] ASoC: fix return value check in mt6351_codec_driver_probe()
Date: Mon, 07 May 2018 01:39:45 +0000	[thread overview]
Message-ID: <1525657185-73163-1-git-send-email-weiyongjun1@huawei.com> (raw)

In case of error, the function dev_get_regmap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
