The patch itself is a two line fix against NULL pointer dereference
like if (!mgr->mst_primary) goto exit. So most likely this is noise.
If this check made it go different code path, this means it would crash
anyway. Otherwise codepath would be exactly same as before.
Also previously v1 version passed, even though new v2 changes are
cosmetic.
(just following instructions to notify you, instead of blindly tapping
"test latest revision" button :D)
