Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley:
"This is a large set of updates, mostly for drivers (qla2xxx [including
support for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa,
be2iscsi, isci, lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas).
There's also a rework for tape adding virtually unlimited numbers of
tape drives plus a set of dif fixes for sd and a fix for a live lock
on hot remove of SCSI devices.
This round includes a signed tag pull of isci-for-3.6
Signed-off-by: James Bottomley <JBottomley@Parallels.com>"
Fix up trivial conflict in drivers/scsi/qla2xxx/qla_nx.c due to new PCI
helper function use in a function that was removed by this pull.
