Subject: drm/i915: handle sdvo input pixel multiplier correctly again
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The sdvo input timing needs to be the actual mode, the sdvo
encoder automatically adjusts for the need of pixel doubling or
quadrupling. This was lost in pipe config conversion of the
pixel multiplier in
commit 6cc5f341b5830541a1b6945435ca90c69b1b8b21

drm/i915: add pipe_config->pixel_multiplier
While at it ditch the intel_ prefix from the crtc in
intel_sdvo_mode_set.
