AOSP CL "Add pcm_get_poll_fd"
https://android.googlesource.com/platform/external/tinyalsa/+/b42510d55bafc96805a44bd6ac40faac28ebd219 commit b42510d55bafc96805a44bd6ac40faac28ebd219 author Dylan Reid <dgreid@chromium.org> Add pcm_get_poll_fd Similar to ALSA snd_pcm_get_poll_fd, this will allow a user to wait for a sound device to have data in a poll(2) call. The hotword thread will use this to wait for a message on its socket or for audio data to become ready.
