[Pkg-alsa-devel] Bug#549531: libasound2: snd_device_name_hint() wrongly calls snd_config_delete()

[John Lindgren]

I've found a couple of more places where snd_config_delete is called
indirectly by snd_device_name_hint, causing failure in another case:

        http://jira.atheme.org/browse/AUDPLUG-101

I am attaching a patch that removes these calls and seems to fix the
problem; however, with this patch, not only the null device but all
devices returned by snd_device_name_hint are listed twice, so a complete
fix may be more complicated.

Peace,
John Lindgren
