atmdev_ops::change_qos() was the hook for renegotiating the traffic parameters of an already-connected VCC, driven from SO_ATMQOS on a connected socket (and previously from the SVC as_modify path, now gone). None of the ATM drivers left in tree implement it - solos-pci only listed change_qos = NULL - so atm_change_qos() always returned -EOPNOTSUPP. Drop the operation and return -EOPNOTSUPP directly.
