NAME

       usb_interface_claimed - returns true iff an interface is claimed

SYNOPSIS

       int usb_interface_claimed  (struct usb_interface * iface);

ARGUMENTS

       iface  the interface being checked

DESCRIPTION

       Returns true (nonzero) iff the interface is claimed, else false (zero).
       Callers must own the driver model’s usb bus readlock. So  driver  probe
       entries  don’t  need extra locking, but other call contexts may need to
       explicitly claim that lock.
