7       eventually

SYNOPSIS

10       int snd_card_free_when_closed(struct snd_card * card);

ARGUMENTS

13       card
14           soundcard structure

DESCRIPTION

17       Unlike snd_card_free, this function doesn't try to release the card
18       resource immediately, but tries to disconnect at first. When the card
19       is still in use, the function returns before freeing the resources. The
20       card resources will be freed when the refcount gets to zero.
