Subject: [PATCH net-next 5/6] netvsc: pass net_device to netvsc_init_buf and netvsc_connect_vsp
Date: Thu, 8 Jun 2017 16:21:22 -0700 [thread overview]
Message-ID: <20170608232123.28366-6-sthemmin@microsoft.com> (raw)
In-Reply-To: <20170608232123.28366-1-sthemmin@microsoft.com>
Don't need to find netvsc_device structure, caller already had it.
Also rearrange declarations.
