From 7e196aa1a011da35a04cb1f161e186563aa8d8db Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 6 Jul 2016 12:18:34 +0000 Subject: clk: sunxi: pll2: Fix return value check in sun4i_pll2_setup() In case of error, the functions clk_register_composite() and clk_register_divider() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
