[Qemu-devel] [PATCH v2 2/2] scsi: fix warning

[Gerd Hoffmann]

hw/scsi-bus.c:758: warning: ‘xfer’ may be used uninitialized in this
function

Isn't true, but older gcc versions (for example 4.1 as shipped in rhel5)
are not clever enougth to figure, so sprinkle in a default: line to make
them happy.
