From 3052cc2c92f11875d111d5b7b9b3ad535b3128b9 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 11 Jun 2012 20:11:40 +0200 Subject: [PATCH] dmaengine: Add wrapper for device_tx_status callback This patch adds a small inline wrapper for the devivce_tx_status callback of a dma device. This makes the source code of users of this function a bit more compact and a bit more legible. E.g.: -status = chan->device->device_tx_status(chan, cookie, &state) +status = dmaengine_tx_status(chan, cookie, &state) Signed-off-by: Lars-Peter Clausen Signed-off-by: Vinod Koul --- include/linux/dmaengine.h | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/include/linux/dmaengine.h b/include/linux/dmaengine.h index ccec62f..9c02a45 100644 --- a/include/linux/dmaengine.h +++ b/include/linux/dmaengine.h @@ -674,6 +674,12 @@ static inline int dmaengine_resume(struct dma_chan *chan) return dmaengine_device_control(chan, DMA_RESUME, 0); } +static inline enum dma_status dmaengine_tx_status(struct dma_chan *chan, + dma_cookie_t cookie, struct dma_tx_state *state) +{ + return chan->device->device_tx_status(chan, cookie, state); +} + static inline dma_cookie_t dmaengine_submit(struct dma_async_tx_descriptor *desc) { return desc->tx_submit(desc); -- 2.7.4
