[Intel-gfx] [PATCH] drm/i915: introduce struct intel_crtc_config
Daniel Vetter

Fri Feb 22 12:05:41 CET 2013
Currently only containing the requested and the adjusted mode. And
only crtc callbacks are converted somewhat to it, encoders will be
done on a as-needed basis (simply too much churn in one patch
otherwise).
Future patches will add tons more useful stuff to this struct,
starting with the very simple.
v2: Store the pipe_config in the intel_crtc, so that the ->mode-set,
->enable and also ->disable have easy access to it.
v3: Store the pipe config in the right crtc ...
v4: Rebased.
v5: Fixup an OOPS when trying to kfree an ERR_PTR.
v6: Used drm_moode_copy and some other small cleanups as suggested
by Ville Syrjälä.
v7: drm_mode_copy preserves the mode id of the destination, so no need
to clear it again (Ville).
