Okay, here it is.
From: Keita Maehara <maehara at debian.org>
These patches enable some YMF743 controls (Tone/3D/IEC958) that won't
be detected with the current version of ALSA.
Signed-off-by: Keita Maehara <maehara at debian.org>

The first one contains only cosmetic changes to share a few
YMF753-specific symbols with YMF743.
