This series consists of the usual driver updates (ufs, qla2xxx, smartpqi, target, zfcp, fnic, mpt3sas, ibmvfc) plus a load of cleanups, a major power management rework and a load of assorted minor updates. There are a few core updates (formatting fixes being the big one) but nothing major this cycle. Signed-off-by: James E.J.
