Valid point and cleans up a bit the ALSA SoC part of the patch.
However I didn't want to limit this generic arch/arm/plat-omap/mcbsp.c
into audio use case only. My change still allows to start transmitter
and receiver exactly at the same time. Might be worth if the
generic McBSP driver is used for something else than audio.
