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 suspects: lpfc, qla2xxx, hisi_sas, megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor updates. There's no major behaviour change or additions to the core in all of this, so the potential for regressions should be small (biggest potential being in the scsi error handler changes)" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (203 commits) scsi: lpfc: Fix hard lock up NMI in els timeout handling. scsi: mpt3sas: remove a stray KERN_INFO scsi: mpt3sas: cleanup _scsih_pcie_enumeration_event() scsi: aacraid: use timespec64 instead of timeval scsi: scsi_transport_fc: add 64GBIT and 128GBIT port speed definitions scsi: qla2xxx: Suppress a kernel complaint in qla_init_base_qpair() scsi: mpt3sas: fix dma_addr_t casts scsi: be2iscsi: Use kasprintf scsi: storvsc: Avoid excessive host scan on controller change scsi: lpfc: fix kzalloc-simple.cocci warnings scsi: mpt3sas: Update mpt3sas driver version. scsi: mpt3sas: Fix sparse warnings scsi: mpt3sas: Fix nvme drives checking for tlr. scsi: mpt3sas: NVMe drive support for BTDHMAPPING ioctl command and log info scsi: mpt3sas: Add-Task-management-debug-info-for-NVMe-drives. scsi: mpt3sas: scan and add nvme device after controller reset scsi: mpt3sas: Set NVMe device queue depth as 128 scsi: mpt3sas: Handle NVMe PCIe device related events generated from firmware. scsi: mpt3sas: API's to remove nvme drive from sml scsi: mpt3sas: API 's to support NVMe drive addition to SML ...
