3.17-stable review patch. If anyone has any objections, please let me know.
------------------ From: Steffen Trumtrar <[email protected]> commit c5bb725ac2d1a13e9e766bf9a16bac986ade17cd upstream. VCCR is used as a trigger to start voltage transitions, so we need to mark it volatile in order to make sure it gets written to hardware every time we set a new voltage. Fixes regulator voltage being stuck at the first voltage set after driver load.
