From: "Nícolas F. R. A. Prado" <[email protected]> Some drivers, like VKMS, only have access to the drm_crtc_state but not the drm_atomic_state during composition of the output framebuffer. Store the state of the CRTC (post-blend) color pipeline client cap in the drm_crtc_state so those drivers can decide whether to look at the color pipeline or the legacy properties for the color management settings to apply.
