Subject: [patch net-next v2 0/9] devlink: features, linecard and reporters locking cleanup

From: Jiri Pirko <jiri@...dia.com>

This patchset does not change functionality.

In the first patch, no longer needed devlink features are removed.

Patches 2-5 removes linecards and reporters locks and reference counting,
converting them to be protected by devlink instance lock as the rest of
the objects.

Patches 6 and 7 convert linecards and reporters dumpit callbacks to
recently introduced devlink_nl_instance_iter_dump() infra.
Patch 8 removes no longer needed devlink_dump_for_each_instance_get()
helper.

The last patch adds assertion to devl_is_registered() as dependency on
other locks is removed.
