Subject: [PATCH] staging: vboxvideo: make a couple of symbols static

From: Colin Ian King <colin.king@...onical.com>

Module parameter vbox_modeset and structure vbox_bo_driver do not need to
be in global scope and hence can be made static.

Cleans up a couple of sparse warnings:
symbol 'vbox_modeset' was not declared. Should it be static?
symbol 'vbox_bo_driver' was not declared. Should it be static?
