    ALSA: pcm: Embed struct device · ef46c7af
    Takashi Iwai authored
    Like previous patches, at this time we embed the struct device into
    PCM object.  However, this needs a bit more caution: struct snd_pcm
    doesn't own one device but two, for both playback and capture!  Thus
    not struct snd_pcm but struct snd_pcm_str object contains the device.
    
    Along with this change, pcm->dev field is dropped for avoiding
    confusion.  It was meant to point to a non-standard parent.  But,
    since now we can touch each struct device directly, we can manipulate
    the parent field easily there, too.
