[PATCH] mmc: at91_mci: correct kunmap_atomic()

From: Nicolas Ferre
Date: Wed Mar 03 2010 - 08:06:45 EST

kunmap_atomic() accepts a pointer to any location in the page so we do not need
the subtraction and cast.

I created a new patch that you can stack at the top of the previous
patch series. I guess that you cannot fold it in other patches as the
kunmap_atomic() correction impacts two different patches.
