From dbb988b4e7eb924ffceaa2a7da6e794c868cb2f3 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sun, 28 Jun 2020 02:30:55 +0000 Subject: [PATCH] clk: qcom: Fix return value check in apss_ipq6018_probe() In case of error, the function dev_get_regmap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
