[igt-dev] [PATCH v2 1/2] drm-uapi/xe: add exec_queue_id member to drm_xe_wait_user_fence structurei

[Bommu Krishnaiah <krishnaiah.bommu@intel.com>]

remove the num_engines/instances members from drm_xe_wait_user_fence structure
and add a exec_queue_id member

Right now this is only checking if the engine list is sane and nothing
else. In the end every operation with this IOCTL is a soft check.
So, let's formalize that and only use this IOCTL to wait on the fence.

exec_queue_id member will help to user space to get proper error code
from kernel while in exec_queue reset
