From b279265cfd677b618f2aee8089073a3e4632d85b Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 11 Mar 2013 09:57:22 -0300 Subject: [PATCH] [media] davinci: vpfe: fix return value check in vpfe_enable_clock() In case of error, the function clk_get() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
