Don't you need to revert d5929835080a60f9119d024fa42f315913942f76 in
order for "drm/i915: Implement WaEdpLinkRateDataReload" to actually be
useful/interesting? Otherwise, what's the point?

Regards,
Jason

Unfortunately there was no clear indication on the revert patch for
the tool to pick, and I hadn't followed that front myself closely.

Should 
483e3d87a37e ("Revert "drm/i915/display: Re-add check for low voltage
sku for max dp source rate"")
have a Fixes tag?

Or should dim consider all reverts as Fixes?

Anyway, I will cherry pick this to our fixes branch for propagation
this week.

Thanks for the heads up,
Rodrigo.
