Subject: 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.

Cheers,

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:
