Date: Thu, 1 Nov 2012 13:33:55 +0800 From: Wei Yongjun <weiyj.lk@...il.com> To: mturquette@...com, peter.ujfalusi@...com Cc: yongjun_wei@...ndmicro.com.cn, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH -next] CLK: clk-twl6040: fix return value check in twl6040_clk_probe() 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.
