Subject: tty/serial: at91: use correct type for dma_sync_*_for_cpu() and dma_sync_*_for_device()
From: Cyrille Pitchen <cyrille.pitchen@xxxxxxxxx>
commit 485819b5b9ed82372dacae775998f3c33717f7fe upstream.
dma_sync_*_for_cpu() and dma_sync_*_for_device() use 'enum dma_data_direction',
not 'enum dma_transfer_direction'
