From e09a716490dbce0b9b7d132d191f1f8785cb5df2 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Fri, 21 Sep 2012 15:19:09 +0800 Subject: [PATCH] ARM: pxa: fix return value check in pxa2xx_drv_pcmcia_probe() In case of error, the function clk_get() returns ERR_PTR() and never returns NULL pointer. The NULL test in the error handling should be replaced with IS_ERR(). dpatch engine is used to auto generated this patch.
