[Intel-gfx] [PATCH v2 20/20] drm/i915: Skip modeset checks when modeset is prevented.

[Maarten Lankhorst]

This will keep the cdclk at boot speed if it's fast enough to drive
the crtc's, and will make init faster.

If this commit causes bugs it's probably a bug related to keeping the
initial mode, because all it does is resetting crtc's.
