commit 06747f21a2d8451f8579b70dbf5d04f11a096ca3 Author: Aaron Durbin adurbin@chromium.org Date: Wed Jun 19 13:20:37 2013 -0500
lynxpoint: expose pch_disable_devfn()
The function to disable devices was formerly named pch_hide_devfn(). This routine was doing more than hiding devices. It was disabling them, i.e. turning them off. Therefore, rename it to pch_disable_devfn(). Also, allow external callers to this function.
