From 4f8f7809e47b6af17032aad66f84d7c16444bd05 Mon Sep 17 00:00:00 2001 From: "weiyongjun (A)" Date: Thu, 28 Dec 2017 02:40:49 +0000 Subject: [PATCH] clk: meson-axg: fix return value check in axg_clkc_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.
