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
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.
