[Intel-gfx] [PATCH v2 1/4] drm/i915: Introduce intel_crtc_needs_fastset()
Ville Syrjala

Fri Oct 21 16:24:39 UTC 2022
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Replace the somewhat obscure crtc_state.update_pipe checks
with a more descriptive thing. Also nicely matches the
intel_crtc_needs_modeset() counterpart for full modesets.
v2: Handle one more case in the fbc code
