Auch, my bad.

So we should

1) revert

commit 0aedb1626566efd72b369c01992ee7413c82a0c5
Author: Ville Syrjälä <ville.syrjala@...ux.intel.com>

    drm/i915: Don't skip request retirement if the active list is empty

in v4.1

and

2) reapply http://patchwork.freedesktop.org/patch/50659 to
drm-intel-next-fixes for v4.2.

Is that right?

BR,
Jani.
