Well actually it will already put e.g. the text console the right way up
since efifb also uses this quirks and gives a hint to fbcon to rotate
the text. So it is not entirely useless.

And since all quirks added to drivers/gpu/drm/drm_panel_orientation_quirks.c
typically get backported having this one in place now will avoid conflicts
with future backports.

That combined with not really seeing a downside to already having
this in place even without the i915 support being sorted out makes
me lean more towards the direction of believing that having this
in 5.17 is fine...

Regards,

Hans
