Subject: [PATCH v4 net-next 05/10] qed: health reporter init deinit seq
Date: Fri, 31 Jul 2020 08:53:56 +0300	[thread overview]
Message-ID: <20200731055401.940-6-irusskikh@marvell.com> (raw)
In-Reply-To: <20200731055401.940-1-irusskikh@marvell.com>

Here we declare health reporter ops (empty for now)
and register these in qed probe and remove callbacks.

This way we get devlink attached to all kind of qed* PCI
device entities: networking or storage offload entity.
