snd_device_name_hint() corrupts the config name space after its call. This results in the error from the suceeding calls of snd_pcm_open() after snd_device_name_hint(). The bug is in try_config() in namehint.c; it calls snd_config_delete(res) but res can be two different objects in the function. One is the object obtained via snd_config_search_definition(), and another is the one from snd_config_search_alias_hooks(). The former is the expanded objects, thus it should be freed. But, the latter is a reference, and must not be freed. This patch adds the check to free or not. Reported-by: John Lindgren <john.lindgren@tds.net> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
