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.
