[alsa-devel] [PATCH RFC 0/3] Embed card device into struct snd_card

The third batch is a more intensive change; now struct device for card-object is embedded in snd_card struct. This makes the presence of the device object presistent, which can be later referred by other devices at the object creation time.

Also, along with this change, the refcounting of the card object was changed just to use the standard device refcount. This needs to move the destructor into the device release callback.

Onre more batch will follow.
