dmaengine: imx-sdma: return sdmac->status in sdma_tx_status()
The sdmac->status was designed to reflect the status of the tx, so simply return it in sdma_tx_status(). Then dma client can call dma_async_is_tx_complete() to know the status of the tx. Signed-off-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
