ASoC: SOF: ipc3-dtrace: Handle race during initialization
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
This series handles the race which can result missing the first position update
after the trace is enabled.
In short: the firmware might send the position update (if we have enough
trace data generated) after the dma-trace is enabled by the TRACE_DMA_PARAMS_EXT
message. Depending on scheduling, load, preemption on Linux side we have seen
that occasionally this first position update got missed and we missed reading it
out.
A new state and more strict handling of host_offset can overcome this issue,
making the dtrace more reliable.
