Subject: [PATCH v5 0/2] drm/panthor: Scheduler fixes for termination failure and timeouts

This patch series includes previously attempted patches to fix panthor
scheduler issues with spurious timeouts and issues when a termination
failed which would lead to a race condition.

---
Changes in v5:
 - Swiched to a patch series to make sure the patch which addresses the
   bug is added as a requirement on the scheduler patch.
Changes in v4:
 - Moved code related to a timeout bug to a separate patch as this
   was not relevant to this change.
Changes in v3:
 - Moved to a patch series to make sure this bug fix happens before the
   changes to the scheduler
Changes in v2:
 - Fixed syntax error

Signed-off-by: Ashley Smith <ashley.smith@...labora.com>

Ashley Smith (2):
  drm/panthor: Reset queue slots if termination fails
  drm/panthor: Make the timeout per-queue instead of per-job
