From: Tejun Heo <tj@xxxxxxxxxx>
Subject: drm: don't use idr_remove_all()
idr_destroy() can destroy idr by itself and idr_remove_all() is being
deprecated. Drop its usage.
* drm_ctxbitmap_cleanup() was calling idr_remove_all() but forgetting
idr_destroy() thus leaking all buffered free idr_layers. Replace it
with idr_destroy().
