Subject: [PATCH 3.19 114/175] tty/serial: at91: use correct type for dma_sync_*_for_cpu() and dma_sync_*_for_device()

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

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

From: Cyrille Pitchen <cyrille.pitchen@...el.com>

commit 485819b5b9ed82372dacae775998f3c33717f7fe upstream.

dma_sync_*_for_cpu() and dma_sync_*_for_device() use 'enum dma_data_direction',
not 'enum dma_transfer_direction'
