Subject[PATCH] few fixes for ymf_sb.c in test13pre3-ac3
Hello, Alan!

Thank you for applying my patch to test13pre3-ac3!

However, there is a glaring bug in drivers/sound/Config.in -
CONFIG_SOUND_YMFPCI is declared twice - once outside CONFIG_OSS, then
inside CONFIG_OSS. I'm removing the later declaration.

CONFIG_SOUND_YMPCI should be disabled if the native driver is compiled
into the kernel. I'm fixing it as well.

Also I tried ymf_sb.c without SUPPORT_UART401_MIDI defined (you have to
edit ymf_sb.c to undefine it). I noticed that the "soundcore" module
would remain in memory with usage count 1 after inserting and removing
"ymf_sb".

It appears that ymf_sb.c should never call sb_dsp_unload with the second
argument being 1 (unload_mpu). It's a 1-byte fix. I decided not to change
the signature of ymf7xxsb_unload_sb for now.

The patch is also available here:
http://www.red-bean.com/~proski/ymf/ymf_sb.patch

P.S. The patch has been tested. My system is running test13pre3-ac3 and
playing nice music :-)

Regards,
Pavel Roskin
