.. we check whether 'xdev' is NULL - but there is no need for
it as the 'dev' check is done before. The 'dev' is embedded in
the 'xdev' so having xdev != NULL with dev being being checked
is not going to happen.

xen-backend. This patch exports xen-backend:* names through modalias and
uevent to autoload them.

The xenbus bus type uses device_create_file to assign all used device
attributes. However it does not remove them when the device goes away.
This patch uses the dev_attrs field of the bus type to specify default
attributes for all devices.
