6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Ernberg <john.ernberg@xxxxxxxx>
commit 8475ffcfb381a77075562207ce08552414a80326 upstream.
If no other USB HCDs are selected when compiling a small pure virutal
machine, the Xen HCD driver cannot be built.
Fix it by traversing down host/ if CONFIG_USB_XEN_HCD is selected.
Fixes: 494ed3997d75 ("usb: Introduce Xen pvUSB frontend (xen hcd)")
