dmaengine: imx-sdma: add terminated list for freed descriptor in worker
Add terminated list for keeping descriptor so that it could be freed in worker without any potential involving next descriptor raised up before this descriptor freed, because vchan_get_all_descriptors get all descriptors including the last terminated descriptor and the next descriptor, hence, the next descriptor maybe freed unexpectly when it's done in worker without this patch. https://www.spinics.net/lists/dmaengine/msg23367.html Signed-off-by: Robin Gong <yibin.gong@nxp.com> Reported-by: Richard Leitner <richard.leitner@skidata.com> Reviewed-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
