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
parents 0f66998f e4b65262
