Subject: [PATCH 05/16] ALSA: oxygen: use new match_string() helper/macro

The change is purely cosmetic at this point in time, but it does highlight
the change done in lib/string.c for match_string().

Particularly for this change, a control mode can be removed/added at a
different index/enum-value, and the match_string() helper will continue
until the end of the array and ignore the NULL.
