    ALSA: pcm: Introduce protocol version field to sw_params · 58900810
    Takashi Iwai authored
    For controlling the new fields more strictly, add sw_params.proto
    field indicating the protocol version of the user-space.  User-space
    should fill the SNDRV_PCM_VERSION value it's built with, then kernel
    can know whether the new fields should be evaluated or not.
    And now tstamp_type field is evaluated only when the valid value is
    set there.  This avoids the wrong override of tstamp_type to zero,
