Subject: [PATCH net-next v1 02/21] bnxt_en: Register devlink instance at the end devlink configuration
Date: Sat, 25 Sep 2021 14:22:42 +0300 [thread overview]
Message-ID: <54d36bce5a78cdb4d51a9eaff6f2216fbbdd1004.1632565508.git.leonro@nvidia.com> (raw)
In-Reply-To: <cover.1632565508.git.leonro@nvidia.com>
From: Leon Romanovsky <leonro@nvidia.com>
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.
