From 68a39a3e9fe1d6f0dfe59e3f4d6bc6765e01c903 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 11 Oct 2017 10:48:44 +0000 Subject: [PATCH] remoteproc: imx_rproc: fix return value check in imx_rproc_addr_init() 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.
