2012-11-17ALSA: Add a reference counter to card instanceTakashi Iwai
commit a0830dbd4e42b38aefdf3fb61ba5019a1a99ea85 upstream. For more strict protection for wild disconnections, a refcount is introduced to the card instance, and let it up/down when an object is referred via snd_lookup_*() in the open ops. The free-after-last-close check is also changed to check this refcount instead of the empty list, too.

2012-01-24ALSA: Fix memory leak on error in snd_compr_set_params()Jesper Juhl
If copy_from_user() does not return 0 we'll leak the memory we allocated for 'params' when that variable goes out of scope. Also a small CodingStyle cleanup: Use braces on both branches of if/else when one branch needs it.
