This breaks the make htmldocs build a bit:
./drivers/gpu/drm/scheduler/gpu_scheduler.c:262: warning: Excess
function parameter 'sched' description in 'drm_sched_entity_flush'
./drivers/gpu/drm/scheduler/gpu_scheduler.c:303: warning: Excess
function parameter 'sched' description in 'drm_sched_entity_fini'
./drivers/gpu/drm/scheduler/gpu_scheduler.c:365: warning: Excess

./drivers/gpu/drm/scheduler/gpu_scheduler.c:730: warning: Excess

./drivers/gpu/drm/scheduler/gpu_scheduler.c:263: warning: Excess

./drivers/gpu/drm/scheduler/gpu_scheduler.c:304: warning: Excess
function parameter 'sched' description in 'drm_sched_entity_fini'
./drivers/gpu/drm/scheduler/gpu_scheduler.c:366: warning: Excess
function parameter 'sched' description in 'drm_sched_entity_destroy'
./drivers/gpu/drm/scheduler/gpu_scheduler.c:731: warning: Excess

Care to fix it?
Thanks, Daniel
