6.6-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.
