Create and initialize an hcd structure
struct usb_hcd * usb_create_shared_hcd(const struct hc_driver * driver, struct device * dev, const char * bus_name, struct usb_hcd * primary_hcd);
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
!in_interrupt
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.
On success, a pointer to the created and initialized HCD structure. On failure (e.g. if memory is unavailable), NULL.
