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.
