failed like this:

In file included from drivers/gpu/drm/i915/i915_debugfs.c:39:

Caused by commit

  564f963eabd1 ("isystem: delete global -isystem compile option")

from the kbuild tree interacting with commit

  b97060a99b01 ("drm/i915/guc: Update intel_gt_wait_for_idle to work with GuC")

I have applied the following patch for today.

Thanks.

This fix-up does not depend on my kbuild tree in any way.

So, the drm maintainer can apply it to his tree.

Perhaps with

Fixes: b97060a99b01 ("drm/i915/guc: Update intel_gt_wait_for_idle to
work with GuC")

OK, so that didn't happen so I will now apply the merge fix up to the
merge of the kbuild tree.

Ping?  I am still applying this ...

Apologies, this fell through a lot of cracks. I applied this to drm-next now.

Matt/John, as author/committer it's your job to make sure issues and
fixes for the stuff you're pushing don't get lost. I'd have expected
John to apply this to at least drm-intel-gt-next (it's not even
there).

Joonas, I think this is the 2nd or 3rd or so issue this release cycle
where some compile fix got stuck a bit because drm-intel-gt-next isn't
in linux-next. Can we please fix that? It probably needs some changes
to the dim script.

Cheers, Daniel
