Subject: [patch net-next 08/12] devlink: put couple of WARN_ONs in devlink_param_driverinit_value_get()
From: Jiri Pirko <jiri@...dia.com>
Put couple of WARN_ONs in devlink_param_driverinit_value_get() function
to clearly indicate, that it is a driver bug if used without reload
support or for non-driverinit param.
