Subject: [PATCH 1/7] staging: vc04_services: Drop pointless stub functions
Date:   Thu,  4 Oct 2018 12:37:41 +0300
Message-Id: <20181004093747.21750-2-tuomas.tynkkynen@iki.fi>
In-Reply-To: <20181004093747.21750-1-tuomas.tynkkynen@iki.fi>
References: <20181004093747.21750-1-tuomas.tynkkynen@iki.fi>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

These functions do nothing besides returning NULL and are unused.
Just drop them.
