Subject: [PATCH v4 11/11] drm/mediatek: add a error return value when clock driver has been prepared
Date: Tue, 2 Oct 2018 16:10:41 +0800	[thread overview]
Message-ID: <20181002081041.32629-12-bibby.hsieh@mediatek.com> (raw)
In-Reply-To: <20181002081041.32629-1-bibby.hsieh@mediatek.com>

DRM driver get the comp->clk by of_clk_get(), we only
assign NULL to comp->clk when error happened, but do
not return the error number.
