Merge branch 'fixes' into misc
Somewhat nasty merge due to conflicts between "33b28357dd00 scsi: qla2xxx: Fix Async GPN_FT for FCP and FC-NVMe scan" and "2b5b96473efc scsi: qla2xxx: Fix FC-NVMe LUN discovery" Merge is non-trivial and has been verified by Qlogic (Cavium) Signed-off-by: James E.J. Bottomley <jejb@linux.vnet.ibm.com>
