dmaengine: imx-sdma: fix up param for the last BD in sdma_prep_slave_sg() As per the reference manual, bit "L" should be set while bit "C" should be cleared for the last buffer descriptor in the non-cyclic chain, so that sdma can stop trying to find the next BD and end the transfer. In case of sdma_prep_slave_sg(), BD_LAST needs to be set and BD_CONT be cleared for the last BD. Signed-off-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
