Man page 9 : usb_driver_release_interface

usb_driver_release_interface - unbind a driver from an interface

void usb_driver_release_interface(struct usb_driver *  driver , struct usb_interface *  iface );

driver
    the driver to be unbound

iface
    the interface from which it will be unbound

This can be used by drivers to release an interface without waiting for their disconnect methods to be called. In typical cases this also causes the driver disconnect method to be called.

This call is synchronous, and may not be used in an interrupt context. Callers must own the device lock, so driver disconnect entries donAqt need extra locking, but other call contexts may need to explicitly claim that lock.
