[alsa-devel] [PATCH] ALSA: snd_ctl_activate_id(): Fix index look-up

[Lars-Peter Clausen]

We want to know the offset for the id that was passed to the function, not
the offset of the first id of the control (which is always 0).

Signed-off-by: Lars-Peter Clausen <lars at metafoo.de>
---
The function seems currently unused, so no need to add this for stable
