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
deviceīs 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 driverīs
probe method.
Callers must own the device lock, so driver probe entries donīt need
extra locking, but other call contexts may need to explicitly claim
that lock.
