NAME
       usb_driver_claim_interface - bind a driver to an interface

SYNOPSIS
       int usb_driver_claim_interface(struct usb_driver * driver, struct usb_interface * iface,
                                      void * priv);

ARGUMENTS
       driver
           the driver to be bound

       iface
           the interface to which it will be bound; must be in the usb device's active
           configuration

       priv
           driver data associated with that interface

DESCRIPTION
       This is used by usb device drivers that need to claim more than one interface on a device
       when probing (audio and acm are current examples). No device driver should directly modify
       internal usb_interface or usb_device structure members.

       Few drivers should need to use this routine, since the most natural way to bind to an
       interface is to return the private data from the driver's probe method.

       Callers must own the device lock, so driver probe entries don't need extra locking, but
       other call contexts may need to explicitly claim that lock.

RETURN
       0 on success.
