NAME
       usb_create_shared_hcd - create and initialize an HCD structure

SYNOPSIS
       struct usb_hcd * usb_create_shared_hcd(const struct hc_driver * driver,
                                              struct device * dev, const char * bus_name,
                                              struct usb_hcd * primary_hcd);

ARGUMENTS
       driver
           HC driver that will use this hcd

       dev
           device for this HC, stored in hcd->self.controller

       bus_name
           value to store in hcd->self.bus_name

       primary_hcd
           a pointer to the usb_hcd structure that is sharing the PCI device. Only allocate
           certain resources for the primary HCD

CONTEXT
       !in_interrupt

DESCRIPTION
       Allocate a struct usb_hcd, with extra space at the end for the HC driver's private data.
       Initialize the generic members of the hcd structure.

RETURN
       On success, a pointer to the created and initialized HCD structure. On failure (e.g. if
       memory is unavailable), NULL.
