[PATCH net-next v1 02/21] bnxt_en: Register devlink instance at the end devlink configuration

Leon Romanovsky
2021-09-25T11:23:17Z

Move devlink_register() to be last command in devlink configuration
sequence, so no user space access will be possible till devlink instance
is fully operable. As part of this change, the devlink_params_publish
call is removed as not needed.

This change fixes forgotten devlink_params_unpublish() too.
