Subject: [PATCH v1 6/7] drm/mediatek: add a error return value when clock driver has been prepared
Date: Mon, 14 May 2018 15:52:42 +0800 [thread overview]
Message-ID: <20180514075243.5442-7-bibby.hsieh@mediatek.com> (raw)
In-Reply-To: <20180514075243.5442-1-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.
