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.
