[Xen-devel] [patch 01/16] xend: pass-through: Only call setupOneDevice() once per device

[Simon Horman <horms@xxxxxxxxxxxx>]

As observed by Dexuan Cui, when PCI devices are passed through at
domain-creation-time setupOneDevice() will be called twice.

Once via setupDevice() and once via econfigureDevice() which
is called in pci_device_configure().

This patch removes the first of these.
