[Intel-gfx] [PATCH 04/13] drm/i915: Adjust .crtc_compute_clock() calling convention

Ville Syrjala ville.syrjala at linux.intel.com
Fri Mar 25 12:31:56 UTC 2022


From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Pass the full atomic state+crtc rather than the redundant
crtc+crtc_state pair. We already need the full atomic state
in the hsw+ codepath anyway.
