code mistakenly used a hardcoded index (codec[1]) instead of
iterating, over the codec array using the loop variable i.
Use codec[i] instead of codec[1] to match the loop iteration.

Shouldn't that have been a bug fix with

Fixes:
and

?

This change likely won't influence on the existing devices, and the
issue has been present from the very beginning of the driver code,
hence no regression.

The stuff in question is about the hardware of over 20 years ago, and
there has been no bug reports about this.  After all, all devices were
with at most two codecs, and this patch is for 3rd and 4th codecs.


thanks,

Takashi
