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

[Stephen Rothwell]

Hi all,

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

Caused by commit

  a6a1f036c74e ("drm/scheduler: Job timeout handler returns status (v3)")

I have used the drm-misc tree from next-20210129 for today.
