Message-ID: <CAPgLHd-BtGhVBHYGW1UFT9wqmnPqmuf9AWkQk6mXG7xSzWqOOA@mail.gmail.com> Date: Fri, 21 Sep 2012 14:35:18 +0800 From: Wei Yongjun <weiyj.lk@...il.com> To: mturquette@...com Cc: yongjun_wei@...ndmicro.com.cn, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH] clk: fix return value check in of_fixed_clk_setup() From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn> 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.
