USB_INTERFACE_CLAIME(9)           Host-Side Data Types and Macro          USB_INTERFACE_CLAIME(9)



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

RETURN
       true (nonzero) iff the interface is claimed, else false (zero).

NOTE
       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.
