[Sound-open-firmware] What is the role of dma_status function?

[Paul Olaru (OSS)]

I think there is an intended use which isn't implemented. If I look at the dai_position function, there is this comment:

/* TODO: improve accuracy by adding current DMA position */

This is probably a place where dma_status would be called in the future/is intended to be called in the future.

The same comment is visible in the host_position function.

I see that all DMA drivers fill in this .status function, but I couldn't find
any users of it.

Any idea?
