Subject[PATCH 3.9-stable] mmc: dw_mmc: fix fifo access for 64-bit
Date
This patch looks like it should be in the 3.9-stable tree, should we apply
it?

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

From: "Seungwon Jeon <tgih.jun@samsung.com>"

commit c09fbd7451b797213b3df8bf077776b9ec33f954 upstream

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