Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380,
qla2xxx, lpfc, libsas, hisi_sas.
In addition there's a set of mostly small updates to the target
subsystem a set of conversions to the generic DMA API, which do have
some potential for issues in the older drivers but we'll handle those
as case by case fixes.
A new myrs driver for the DAC960/mylex raid controllers to replace the
block based DAC960 which is also being removed by Jens in this merge
window.
Plus the usual slew of trivial changes"
[ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even
wonder. There's also a "myrb" driver, where the 'b' stands for
'block'. Truly, somebody has got mad naming skillz. - Linus ]
