3.0-stable review patch. If anyone has any objections, please let us know.
------------------ From: Carolyn Wyborny <[email protected]> commit 064b43304ed8ede8e13ff7b4338d09fd37bcffb1 upstream. Register writes followed by a delay are required to have a flush before the delay in order to commit the values to the register. Without the flush, the code following the delay may not function correctly.
