From 536eb97abeba857126ad055de5923fa592acef25 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 4 Mar 2021 10:04:23 +0000 Subject: cpufreq: qcom-hw: Fix return value check in qcom_cpufreq_hw_cpu_init() In case of error, the function ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
