Subject: [PATCH 3.9-stable] mmc: dw_mmc: fix fifo access for 64-bit

This patch looks like it should be in the 3.9-stable tree, should we apply
it?

------------------

From: "Seungwon Jeon <[email protected]>"

commit c09fbd7451b797213b3df8bf077776b9ec33f954 upstream

mci_writew causes a failure of fifo access for 64-bit.
mci_writeq is correct.

It doesn't apply to the 3.9 tree, so it's going to be bit hard to do
this...
