[PATCH] Add MODULE_ALIAS for Xen pciback. (v1)

[Konrad Rzeszutek Wilk]

Most of the drivers had this in them except the Xen pciback.
This patch fixes that.

      xen-pciback: Add MODULE_ALIAS for pciback.

[PATCH] xen-pciback: Add MODULE_ALIAS for pciback.

[Konrad Rzeszutek Wilk]

The rest of the Xen device drivers use an module alias
to load devices when they shop up in XenBus.

This is done for the rest of them but hadn't been done
for Xen PCI back. This patch fixes it.

Isn't that xen-backend:pci already the right thing for a backend device?
xen: is for frontends, I thought.

The patch turned out to be even more trivial than expected ;-)

Is this what we expected to be pending work for the item "device
hotplug (MODULE_ALIAS)" on the upstream TODO list?

http://wiki.xenproject.org/wiki/XenParavirtOps#Upstream_delta_details

This was simply to just auto load that driver when needed right?

Also as for actual PCI device hotplug support:

http://wiki.xen.org/wiki/Xen_PCI_Passthrough#Hotplug

I don't think we need a delta for that do we?
