Subject: [RFC 8/8] drm/exynos: simplify set_pixfmt() in DECON and FIMD drivers
Date: Tue,  4 Apr 2017 16:03:01 +0200	[thread overview]
Message-ID: <1491314581-18086-9-git-send-email-tjakobi@math.uni-bielefeld.de> (raw)
In-Reply-To: <1491314581-18086-1-git-send-email-tjakobi@math.uni-bielefeld.de>

DRM core already checks the validity of the pixelformat.
