Fix TGL REVID macros to fetch correct display/gt stepping based
on SOC rev id from INTEL_REVID() macro. Previously, we were just
returning the first element of the revid array instead of using
the correct index based on SOC rev id.

Both patches applied. Thanks!

Jani, maybe now you can rebase your patch to get rid of the extern ?

Yes, thanks for the irq so I can stop polling. ;)

Huh, why were these applied to drm-intel-gt-next? It's much more about
driver core code than gt.

sigh... by mistake. At the time as was mainly thinking about the WAs
that are affected by these and thought it would belong to gt.

what now? Do we apply in to drm-intel-next as well or wait for a backmerge?

sorry,

Maybe I'll do the refactoring in gt-next as well. Or wait for the
backmerge. *shrug*

Don't worry about it.
