From 393151c211006cc5ac6af26ecd9982dd916a8104 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 26 Aug 2019 12:00:03 +0000 Subject: [PATCH] ASoC: SOF: imx8: Fix return value check in imx8_probe() 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.
