We also need a copy in the crtc itself so the vblank code can get at it. We already have scanline_offset in there for a similar reason, as well as the vblank->hwmode which is assigned via drm_calc_timestamping_constants(). Fortunately we now have a nice place for doing the crtc_state->crtc copy in intel_crtc_update_active_timings() which gets called both for modesets and init/resume readout. The one slightly iffy spot is the INHERITED flag which we want to preserve until userspace/fb_helper does the first proper commit after actually calling .detecti() on the connectors. Otherwise we don't have the full sink capabilities (audio,infoframes,etc.) when .compute_config() gets called and thus we will fail to enable those features when the first userspace commit happens. The only internal commit we do prior to that should be from intel_initial_commit() and there we can simply preserve the INHERITED flag from the readout.
