3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Axel Lin <[email protected]> commit e8d9897ff064b1683c11c15ea1296a67a45d77b0 upstream. commit 81d0a6ae7befb24c06f4aa4856af7f8d1f612171 upstream. Use DIV_ROUND_UP to prevent truncation by integer division issue. This ensures we return enough delay time.
