From 4ee87930e4e26a1f873086ab24d53b946787c63f Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Tue, 8 Mar 2016 01:41:29 +0200 Subject: [PATCH] clk: at91: fix check of clk_register() returned value commit cb0ceaf77d93964a0d00477c79f4499123f6159c upstream. The clk_register() function returns a valid pointer to struct clk or ERR_PTR() error code, this makes a check for returned NULL value useless and may lead to oops on error path.
