Subject: [PATCH] clk: samsung: exynos5420: Remove useless check for return value of samsung_clk_init
Date: Sun,  8 May 2016 11:24:56 +0200	[thread overview]
Message-ID: <1462699496-16646-1-git-send-email-krzk@kernel.org> (raw)

The samsung_clk_init() cannot return NULL. Either it returns allocated
memory or it panics.
