Subject: [PATCH -next] ASoC: mmp-sspa: Fix return value check in asoc_mmp_sspa_probe()
Date: Wed, 27 May 2020 03:02:10 +0000	[thread overview]
Message-ID: <20200527030210.124393-1-weiyongjun1@huawei.com> (raw)

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