Subject: [patch net-next v2 10/13] net: devlink: add not cleared type warning to port unregister
Date: Mon,  3 Oct 2022 12:52:01 +0200	[thread overview]
Message-ID: <20221003105204.3315337-11-jiri@resnulli.us> (raw)
In-Reply-To: <20221003105204.3315337-1-jiri@resnulli.us>

From: Jiri Pirko <jiri@nvidia.com>

By the time port unregister is called. There should be no type set. Make
sure that the driver cleared it before and warn in case it didn't. This
enforces symmetricity with type set and port register.
