Subject: [PATCH net-next 08/10] netvsc: remove unnecessary check for NULL hdr
Date: Wed, 9 Aug 2017 17:46:10 -0700 [thread overview]
Message-ID: <20170810004612.22163-9-sthemmin@microsoft.com> (raw)
In-Reply-To: <20170810004612.22163-1-sthemmin@microsoft.com>
The function init_page_array is always called with a valid pointer
to RNDIS header. No check for NULL is needed.
