[Intel-gfx] [PATCH 05/15] drm/i915: Enable DVO between mode_set and dpms hooks

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

To more closely match the IEGD ns2501 driver behaviour, call the
mode_set hook while the DVO port is still disabled, then enable the DVO
port, and finally call the dpms hook.
