drm/msm: Split submit_lookup_objects() into two loops First loop does copy_from_user() without the table lock held and just stores the handle. Second loop looks up buffer objects with the table_lock held without potentially blocking or faulting. This lets us clean up a bunch of custom, non-faulting copy_from_user() code.
