[PATCH v2 5/6] pc-bios/s390-ccw: write IPLB location for non-net virtio devices

[jrossi@linux.ibm.com]

From: Jared Rossi <jrossi@linux.ibm.com>

When IPL type is PCI, cutype is unknown, so the IPLB location does not
get written to lowcore.  Instead of checking cutype, check if the device
is virtio generically, which covers both CCW and PCI variants.  Net devices
are excluded.
