Make sure that the CRTC state is reset correctly, as expected after disabling the CRTC. In particular this change will: - Zero all the CSC blob pointers after intel_crtc_free_hw_state() has freed them. - Zero the shared DPLL and port PLL pointers and clear the corresponding CRTC reference flag in the PLL state. - Reset all the transcoder and pipe fields. v2: - Reset fully the CRTC state. (Ville) - Clear pipe active flags in the DPLL state. v3: - Clear only the CRTC reference flag and add a helper for this. (Ville) v4: - Rebased on previous patch, adding intel_unreference_shared_dpll_crtc() separately.
