[PATCH v2] drm/scheduler: quieten kernel-doc warnings

[PATCH v2] drm/scheduler: quieten kernel-doc warnings

[Randy Dunlap]

Fix kernel-doc warnings in gpu_scheduler.h and sched_main.c.

Quashes these warnings:

include/drm/gpu_scheduler.h:332: warning: missing initial short description on line:
 * struct drm_sched_backend_ops
include/drm/gpu_scheduler.h:412: warning: missing initial short description on line:
 * struct drm_gpu_scheduler
include/drm/gpu_scheduler.h:461: warning: Function parameter or member 'dev' not described in 'drm_gpu_scheduler'

drivers/gpu/drm/scheduler/sched_main.c:201: warning: missing initial short description on line:
 * drm_sched_dependency_optimized
drivers/gpu/drm/scheduler/sched_main.c:995: warning: Function parameter or member 'dev' not described in 'drm_sched_init'

Fixes: 2d33948e4e00 ("drm/scheduler: add documentation")
Fixes: 8ab62eda177b ("drm/sched: Add device pointer to drm_gpu_scheduler")
Fixes: 542cff7893a3 ("drm/sched: Avoid lockdep spalt on killing a processes")
