[Intel-gfx] [PATCH 0/3] drm/i915: Fix Wa_22016122933 implementation

[Andi Shyti]

Hi Jonathan,

pushed in drm-intel-gt-next.

I added two links to the commit logs: the first one refers to
this series, while the second refers to the series sent to CI
which includes the rebase conflict fix.

Hope this is fine.

Thanks,
Andi
