+Subject: [PATCH] vcsm: Reduce scope of local functions
+
+The functions:
+
+  vc_vchi_sm_send_msg
+  vc_sm_ioctl_alloc
+  vc_sm_ioctl_alloc_share
+  vc_sm_ioctl_import_dmabuf
+
+Are declared without a prototype. They are not used outside of this
+module, thus - convert them to static functions.
+
+Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
