NAME

6       usb_interface_claimed - returns true iff an interface is claimed
7

SYNOPSIS

9       int usb_interface_claimed(struct usb_interface * iface);
10

ARGUMENTS

12       iface
13           the interface being checked
14

DESCRIPTION

16       Returns true (nonzero) iff the interface is claimed, else false (zero).
17       Callers must own the driver model´s usb bus readlock. So driver probe
18       entries don´t need extra locking, but other call contexts may need to
19       explicitly claim that lock.
