From cdfed3b21f10ecd1566c7d5b8d40f05b18d52bda Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Fri, 21 Sep 2012 14:35:18 +0800 Subject: [PATCH] clk: fix return value check in of_fixed_clk_setup() In case of error, the function clk_register_fixed_rate() returns ERR_PTR() not NULL pointer. The NULL test in the return value check should be replaced with IS_ERR(). dpatch engine is used to auto generated this patch.
