usb_driver_claim_interface — bind a driver to an interface
int usb_driver_claim_interface ( | struct usb_driver * driver, |
| struct usb_interface * iface, | |
void * priv); |
driverthe driver to be bound
ifacethe interface to which it will be bound; must be in the usb device's active configuration
privdriver data associated with that interface
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.
