From c6b69bf143734a797b45e4728dc5ad80586d206c Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 29 Oct 2019 09:57:56 -0700 Subject: [PATCH] soc: ti: omap-prm: fix return value check in omap_prm_probe() In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
