Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Five small fixes, all in drivers.
Most of these are error leg freeing issues, with the only really user
visible one being the zfcp fix"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: iscsi: Fix possible memory leak when device_register() failed
scsi: zfcp: Fix double free of FSF request when qdio send fails
scsi: scsi_debug: Fix possible UAF in sdebug_add_host_helper()
scsi: target: tcm_loop: Fix possible name leak in tcm_loop_setup_hba_bus()
scsi: mpi3mr: Suppress command reply debug prints
