Can't compile kernel with snd_RELENG_5_20051022_055.diff

[Ales]

Hello again.
Here is what I tried:/

/rm -rf /usr/src/sys/dev/sound/
rm -f /usr/src/sys/conf/file /usr/src/sys/sys/soundcard.h//
rm -f /usr/src/sys/modules/sound/sound/Makefile

re-cvsup to get clean source.

cd /usr/src/ && patch -p0 < snd_RELENG_5_20051022_055.diff

It is the same with .tar.gz file from 
http://people.freebsd.org/~ariff/snd_RELENG_5_20051009_055.tar.gz

after "make buildkernel" the error apears

/usr/src/sys/dev/sound/pcm/sndstat.c: In function `sndstat_uninit':
/usr/src/sys/dev/sound/pcm/sndstat.c:364: error: `s' undeclared (first 
use in this function)
/usr/src/sys/dev/sound/pcm/sndstat.c:364: error: (Each undeclared 
identifier is reported only once
/usr/src/sys/dev/sound/pcm/sndstat.c:364: error: for each function it 
appears in.)
/usr/src/sys/dev/sound/pcm/sndstat.c: At top level:
/usr/src/sys/dev/sound/pcm/sndstat.c:371: warning: no previous prototype 
for 'sndstat_busy'
*** Error code 1

Stop in /usr/obj/usr/src/sys/GENERIC.
*** Error code 1

Stop in /usr/src.

Can anyone help me please?
