From dc62f951a6a8490bcccc7b6de36cd85bd57be740 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 17 Apr 2019 02:30:59 +0000 Subject: [PATCH] regulator: stm32-pwr: Fix return value check in stm32_pwr_regulator_probe() In case of error, the function of_iomap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
