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.
