From cddd74db8d42b953a0612810f07c99e73deab185 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 19 Jul 2016 11:21:56 +0000 Subject: watchdog: pic32-wdt: Fix return value check in pic32_wdt_drv_probe() In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
