[ALSA] Fix disconnection of proc interface
- Add the linked list to each proc entry to enable a single-shot disconnection (unregister) - Deprecate snd_info_unregister(), use snd_info_free_entry() - Removed NULL checks of snd_info_free_entry() Signed-off-by: Takashi Iwai <[email protected]> Signed-off-by: Jaroslav Kysela <[email protected]>
