Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI fixes from James Bottomley:

- add support for new devices (ufs, mvsas)

- a major set of fixes in lpfc

- get rid of a driver specific ioctl in pcmraid

- a major rework of aha152x to get rid of the scsi_pointer.

- minor fixes and obvious changes including several spelling updates.
