Rewrite the ring buffer transfer functions to copy one period at a time then call snd_pcm_period_elapsed(). This reduces the latency of transferring the initial ~2sec of audio after hotword detect since audio samples are available for userspace earlier.
This is fixing an earlier patch in the series, why not squash it in?
