ASoC: SOF: Intel: hda-stream: export stream_get_position() helper

plbossart · broonie · commit 9e7fd21ab03e · 2024-05-05T23:45:43.000+09:00
Export this helper so that we can report the DPIB position if the BPT DMA do not complete - this is very useful to see if the DMA started or gets stuck somehow with invalid bandwidth configurations.
