SCSI misc on 20201216

Browse Source 
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.
