[RFC 0/3] Simpler and more consistent handling of entities on missing hw blocks

[Tvrtko Ursulin <tvrtko.ursulin@igalia.com>]

Trying to consolidate how entity creation and/or submission is rejected when
underlying hw ip block is missing.

Amdgpu appears to be the only user which can pass zero schedulers, or a single
NULL scheduler to drm_sched_entity_init(), so if I did not miss something subtle
and the first two patches are okay, then the last one removes handling for that
special case from the DRM scheduler.

Tvrtko Ursulin (3):
  drm/amdgpu: Reject impossible entities early
  drm/amdgpu: Remove redundant missing hw ip handling
  drm/sched: Disallow initializing entities with no schedulers
