This doesn't apply:

patching file drivers/scsi/virtio_scsi.c
Hunk #1 succeeded at 677 (offset 196 lines).
Hunk #2 FAILED at 494.
Hunk #3 succeeded at 736 (offset 198 lines).
1 out of 3 hunks FAILED -- saving rejects to file
drivers/scsi/virtio_scsi.c.rej

could you respin against scsi-misc head?

Thanks,
