[Intel-gfx] [PATCH 3/4] drm/i915: Make DRRS debugfs per-crtc/connector
Ville Syrjala

Wed Sep 28 10:44:33 UTC 2022
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Since I already broke anything that relied on the old contents
of the DRRS debugfs files might as well finish the breakage
and convert the files to be per-crtc/connector so we don't need
to have annoying code in igt to parse these.
