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

Hi all,

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

drivers/gpu/drm/nouveau/nvkm/subdev/mmu/vmmgp100.c: In function 'gp100_vmm_fault_cancel':
drivers/gpu/drm/nouveau/nvkm/subdev/mmu/vmmgp100.c:491:6: error: unused variable 'inst' [-Werror=unused-variable]
  491 |  u32 inst, aper;
      |      ^~~~
cc1: all warnings being treated as errors

Caused by commit

  404046cf4805 ("drm/nouveau/mmu/gp100-: drop unneeded assignment in the if condition.")

I have used the drm-misc tree from next-20211011 for today.

uhh, that's on me. I will send out a patch today. I just noticed that
the config file I used for testing had WERROR disabled.

I already wrote the patch and pushed it:

We'll need CONFIG_DRM_XE=m enabled in drm-rerere/drm-misc-*_defconfig,
and get people to use that.

Indeed. Not even drm-misc itself compiles with xe enabled. I'll ping
drm-misc maintainers.

I think it should have been done in commit 4db102dcb039 ("Merge drm/drm-next into drm-misc-next")
when drm-next merged back into drm-misc-next. Now one option is probably a
commit on drm-misc-next with this content:
https://cgit.freedesktop.org/drm-tip/tree/fixups/drm-misc-next.patch?h=rerere-cache&id=c39c6e3d74203820ef630884a5323237696bd36c
