Subject: ALSA: snd_ctl_activate_id(): Fix index look-up
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=31584ed18c073176a7ad96ddbfd09765e21e813d;p=linux-beck.git

ALSA: snd_ctl_activate_id(): Fix index look-up

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).
