Function del_timer() does not guarantee that timer was really deleted.
If the timer handler is beeing executed at the moment, the function
does nothing. So, it's possible to use already freed memory in the handler:

Using __bitwise and typedefs for the attributes of snd_device struct
isn't so useful, and rather it worsens the readability.  Let's drop
them and use the straightforward enum.

Instead of SNDRV_DEV_LOWLEVEL, use SNDRV_DEV_CODEC type for mixer
objects so that they are managed in a proper release order.

Drop the own refcount but use the standard device refcounting via
get_device() and put_device().  Introduce a new completion to snd_card
instead of the wait queue for syncing the last release, which is used
in snd_card_free().

As prepared in the previous patch, we are ready to create a device
struct for the card object in snd_card_create() now.  This patch
changes the scheme from the old style to:

- embed a device struct for the card object into snd_card struct,
- initialize the card device in snd_card_create() (but not register),
- registration is done in snd_card_register() via device_add()

The actual card device is stored in card->card_dev.  The card->dev
pointer is kept unchanged and pointing to the parent device as before
for compatibility reason.
