3.5.7.4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Axel Lin <axel....@ingics.com>
commit 81d0a6ae7befb24c06f4aa4856af7f8d1f612171 upstream.
Use DIV_ROUND_UP to prevent truncation by integer division issue.
This ensures we return enough delay time.
