Subject: [PATCH 1/2] drivers/i2c/busses: use correct type for dma_map/unmap
Date: Mon, 21 Jul 2014 11:42:03 +0200 [thread overview]
Message-ID: <1405935725-10457-2-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1405935725-10457-1-git-send-email-wsa@the-dreams.de>
dma_{un}map_* uses 'enum dma_data_direction' not 'enum dma_transfer_direction'.
