Message-ID: <CAPgLHd-0wYjWxWrmLdc+an0RVfEicv3QBEtvsuvQtphti3phdw@mail.gmail.com> Date: Fri, 21 Sep 2012 14:14:25 +0800 From: Wei Yongjun <weiyj.lk@...il.com> To: kernel@...gutronix.de, linux@....linux.org.uk Cc: yongjun_wei@...ndmicro.com.cn, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH] ARM: imx: fix the return value check in imx_clk_busy_divider() From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn> In case of error, the function clk_register() returns ERR_PTR() no 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.
