Hi all,

After merging the amdgpu tree, today's linux-next build (powerpc
allyesconfig) failed like this:

In file included from <command-line>:
include/drm/gpu_scheduler.h:98:21: error: field 'entity_idle' has incomplete type
   98 |  struct completion  entity_idle;
      |                     ^~~~~~~~~~~

followed by lots of similar errors.

Caused by commit

  83a7772ba223 ("drm/sched: Use completion to wait for sched->thread idle v2.")

I added the following patch for today.
