From 2a65f7e2772613debd03fa2492e76a635aa04545 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 8 Mar 2021 12:30:31 +0000 Subject: [PATCH] clocksource/drivers/ingenic_ost: Fix return value check in ingenic_ost_probe() In case of error, the function device_node_to_regmap() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
