fix (oops in all legacy host drivers)."
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
[SCSI] virtio_scsi: fix TMF use-after-free
[SCSI] fix oops in all legacy host adapters caused by 6f381fa
[SCSI] qla2xxx: Update version number to 8.04.00.03-k.
[SCSI] qla2xxx: Properly check for current state after the fabric-login request.
[SCSI] qla2xxx: Proper completion to scsi-ml for scsi status task_set_full and busy.
[SCSI] qla2xxx: Block flash access from application when device is initialized for ISP82xx.
[SCSI] qla2xxx: Fix reset time out as qla2xxx not ack to reset request.
