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.
