Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull first round of SCSI updates from James Bottomley: "The patch set is mostly driver updates (usf, zfcp, lpfc, mpt2sas, megaraid_sas, bfa, ipr) and a few bug fixes. Also of note is that the Buslogic driver has been rewritten to a better coding style and 64 bit support added. We also removed the libsas limitation on 16 bytes for the command size (currently no drivers make use of this)" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (101 commits) [SCSI] megaraid: minor cut and paste error fixed. [SCSI] ufshcd-pltfrm: remove unnecessary dma_set_coherent_mask() call [SCSI] ufs: fix register address in UIC error interrupt handling [SCSI] ufshcd-pltfrm: add missing empty slot in ufs_of_match[] [SCSI] ufs: use devres functions for ufshcd [SCSI] ufs: Fix the response UPIU length setting [SCSI] ufs: rework link start-up process [SCSI] ufs: remove version check before IS reg clear [SCSI] ufs: amend interrupt configuration [SCSI] ufs: wrap the i/o access operations [SCSI] storvsc: Update the storage protocol to win8 level [SCSI] storvsc: Increase the value of scsi timeout for storvsc devices [SCSI] MAINTAINERS: Add myself as the maintainer for BusLogic SCSI driver [SCSI] BusLogic: Port driver to 64-bit. [SCSI] BusLogic: Fix style issues [SCSI] libiscsi: Added new boot entries in the session sysfs [SCSI] aacraid: Fix for arrays are going offline in the system. System hangs [SCSI] ipr: IOA Status Code(IOASC) update [SCSI] sd: Update WRITE SAME heuristics [SCSI] fnic: potential dead lock in fnic_is_abts_pending() ...
