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. Signed-off-by: Kristian H. Kristensen <hoegsberg@chromium.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
