Message-ID: <CAPgLHd8Brw7dEffrj+xAM60ssgi3pJyMTGX+icPR7ZrZKz-vOQ@mail.gmail.com> Date: Sun, 7 Oct 2012 22:02:09 +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 sirfsoc_of_clk_init() From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn> In case of error, the function clk_register() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). dpatch engine is used to auto generate this patch.
