As you're touching this anyway, how about fixing the other minor
issues with it too? E.g.

dev_err(&dev->dev, "Device appears to be assigned to dom%d!"
" Overwriting the ownership, but beware.\n",
xen_find_device_domain_owner(dev));

(a native English speaker may want to comment the "but beware"
part - it reads odd for me).
