usb_driver_claim_int(9)
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.
