Pull more SCSI updates from James Bottomley: "The only new stuff which missed the first pull request is an update to the UFS driver. The rest is an assortment of bug fixes and minor tweaks which appeared recently (some are fixes for recent code and some are stuff spotted recently by the checkers or the new gcc-6 compiler [most of Arnd's stuff])" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (32 commits) scsi_common: do not clobber fixed sense information scsi: ufs: select CONFIG_NLS scsi: fc: use get/put_unaligned64 for wwn access fnic: move printk()s outside of the critical code section. qla2xxx: avoid maybe_uninitialized warning megaraid_sas: add missing curly braces in ioctl handler lpfc: fix misleading indentation scsi_transport_sas: add 'scsi_target_id' sysfs attribute scsi_dh_alua: uninitialized variable in alua_check_vpd() scsi: ufs-qcom: add printouts of testbus debug registers scsi: ufs-qcom: enable/disable the device ref clock scsi: ufs-qcom: set PA_Local_TX_LCC_Enable before link startup scsi: ufs: add device quirk delay before putting UFS rails in LPM scsi: ufs: fix leakage during link off state scsi: ufs: tune UniPro parameters to optimize hibern8 exit time scsi: ufs: handle non spec compliant bkops behaviour by device scsi: ufs: add retry for query descriptors scsi: ufs: add error recovery after DL NAC error scsi: ufs: make error handling bit faster scsi: ufs: disable vccq if it's not needed by UFS device ...
