-commit 4703049f768fc1c1caac754134118bee1a3af189 upstream.
-
-There is Intel specific workaround DPCD address containing workaround for
-case where SDP is on prior line. Apply this workaround according to values
-in the offset.

-Fixes: 61e887329e33 ("drm/i915/xelpd: Handle PSR2 SDP indication in the prior scanline")
