Subject: linux-next: build failure after merge of the drm tree

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.

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Fri, 20 Aug 2021 12:24:19 +1000
Subject: [PATCH] drm/i915: use linux/stddef.h due to "isystem: trim/fixup stdarg.h and other headers"
