Merge remote-tracking branch 'bonzini/scsi-next' into staging
* bonzini/scsi-next:
scsi: add support for ATA_PASSTHROUGH_xx scsi command
esp: add missing const on TypeInfo structures
esp: enable for all PCI machines
Revert "megasas: disable due to build breakage"
megasas: static SAS addresses
scsi-disk: fix compilation with DEBUG_SCSI
megasas: Update function megasys_scsi_uninit
SCSI: STARTSTOPUNIT only eject/load media if powercondition is 0
SCSI: Update the sense code for PREVENT REMOVAL errors
