Subject: [PATCH] staging: vc04_services: remove empty functions
Message-ID: <ZTD677iqMkRPxT27@lab-ubuntu>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

The functions vchiq_debugfs_init(), vchiq_debugfs_deinit(),
vchiq_debugfs_add_instance(), and vchiq_debugfs_remove_instance()
are declared and defined but contains no code or statements.
They do nothing.
