Subject: [patch net-next v4 00/10] devlink: linecard and reporters locking cleanup

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

This patchset does not change functionality.

Patches 1-6 removes linecards and reporters locks and reference counting,
converting them to be protected by devlink instance lock as the rest of
the objects.

Patches 7 and 8 convert linecards and reporters dumpit callbacks to
recently introduced devlink_nl_instance_iter_dump() infra.
Patch 9 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.

---
v3->v4:
- patch #1 was removed from the set and will be sent as a part of
  another patchset
v2->v3:
- see individual patches for changelog, mainly original patch #4 was
  split into 3 patches for easier review
