Subject: [PATCH v5 10/14] drm: mgag200: remove dead code and pointless local lut storage
Date: Thu, 13 Jul 2017 18:25:34 +0200 [thread overview]
Message-ID: <20170713162538.22788-11-peda@axentia.se> (raw)
In-Reply-To: <20170713162538.22788-1-peda@axentia.se>
The redundant fb helpers .load_lut, .gamma_set and .gamma_get are
no longer used. Remove the dead code and hook up the crtc .gamma_set
to use the crtc gamma_store directly instead of duplicating that
info locally.
Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
Signed-off-by: Peter Rosin <peda@axentia.se>
