    Subjectlinux-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:

    Caused by commit

    c10983e14e8f ("drm/scheduler: Job timeout handler returns status (v3)")

    I have used the drm-misc tree from next-20210209 for today.
