Subject: [PATCH 5.3 026/135] ASoC: ti: sdma-pcm: Add back the flags parameter for non standard dma names

From: Peter Ujfalusi <peter.ujfalusi@...com>

[ Upstream commit dd7e8d903e1eef5a9234a2d69663dcbfeab79571 ]

When non standard names are used it is possible that one of the directions
are not provided, thus the flags needs to be present to tell the core that
we have half duplex setup.
