    ALSA: hda - Revive snd_hda_get_conn_list() · ee8e765b
    Takashi Iwai authored
    Manage the connection list cache using linked lists instead of
    snd_array, and revive snd_hda_get_conn_list() again, so that we don't
    have to keep the expanded values locally.
    This will reduce the stack usage by recursive call of
    snd_hda_get_conn_index() or parse_nid_path() of the generic parser.
    The list management doesn't include any mutex protection, thus the
    caller needs to take care of race appropriately.
