Subject: [PATCH net-next v1 05/21] net: hinic: Open device for the user access when it is ready

From: Leon Romanovsky <leonro@...dia.com>

Move devlink registration to be the last command in device activation,
so it opens the driver to accept such devlink commands from the user
when it is fully initialized.
