Subject: [PATCH -next] ASoC: SOF: imx8: Fix return value check in imx8_probe()
Date: Mon, 26 Aug 2019 12:00:03 +0000	[thread overview]
Message-ID: <20190826120003.183279-1-weiyongjun1@huawei.com> (raw)

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

Fixes: 202acc565a1f ("ASoC: SOF: imx: Add i.MX8 HW support")
Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com>
