Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi 

Pull SCSI fixes from James Bottomley:
 "This is seven basic fixes (plus one MAINTAINER update) which came in
  close to the merge window"

* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  ipr: Fix error return code in ipr_probe_ioa()
  fcoe: add missing destroy_workqueue() on error in fcoe_init()
  lpfc: Fix possible NULL pointer dereference
  fcoe: Use default VLAN for FIP VLAN discovery
  ipr: Wait to do async scan until scsi host is initialized
  MAINTAINERS: Update cxlflash maintainers
  cxlflash: Verify problem state area is mapped before notifying shutdown
  lpfc: fix oops in lpfc_sli4_scmd_to_wqidx_distr() from lpfc_send_taskmgmt()
