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

Content-Transfer-Encoding: 7BIT
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
