3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Patrik Jakobsson <[email protected]> commit f40ebd6bcbbd0d30591f42dc16be52b5086a366b upstream. According to PRM we need to disable hsync and vsync even though ADPA is disabled. The previous code did infact do the opposite so we fix it.
