[PATCH net-next v1 0/8] devlink: retain error in struct devlink_fmsg

Extend devlink fmsg to retain error, and return it at each subsequent call
(patch 1), so drivers could omit all but last error checks (the rest of
the patches).

I would be happy to re-send patches 3-8 as separate to their vendors
maintainers, to don't block merge of 1st one (as they are kind of
illustration here).

Especially mlx5 is massive thanks to custom fmsg API wrappers,
thus it's last.
