Subject: [PATCH 3.14 35/88] drivers/i2c/busses: use correct type for dma_map/unmap

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Wolfram Sang <wsa@...-dreams.de>

commit 28772ac8711e4d7268c06e765887dd8cb6924f98 upstream.

dma_{un}map_* uses 'enum dma_data_direction' not 'enum dma_transfer_direction'.
