[Intel-gfx] [PATCH 02/11] drm/i915: Make the CRTC wrt. CSC state consistent during sanitize-disabling

[Imre Deak]

intel_crtc_free_hw_state() frees all the Intel specific CSC blobs in the
CRTC state, but the next memset() will only clear the corresponding
pointers for the ones stored in intel_crtc_state:hw. Clear the ones
stored in intel_crtc_state as well. Also sync the UAPI state with the HW
state after the HW state was reset. This will reset the uapi.active
flag as well, so no need to do this separately. Syncing the state will
create a new umode blob, so move deleting the blob after the sync call.
