Hi all,

After merging the drm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

In file included from drivers/gpu/drm/i915/i915_debugfs.c:39:
drivers/gpu/drm/i915/gt/intel_gt_requests.h:9:10: fatal error: stddef.h: No such file or directory
    9 | #include <stddef.h>
      |          ^~~~~~~~~~

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.
