Hello!
The last change to alsa-kernel/core/sound.c doesn't work with
Linux 2.4.20-pre8 with devfs support enabled:
# depmod -ae
depmod: *** Unresolved symbols in /lib/modules/2.4.20-pre8/kernel/sound/acore/snd.o
depmod: devfs_find_and_unregister
There is no "devfs_find_and_unregister" in the sources of Linux
2.4.20-pre8. Maybe that patch was meant for Linux 2.5.x?
The revision of alsa-kernel/core/sound.c that introduces
devfs_find_and_unregister is 1.22:
revision 1.22
date: 2002/09/26 12:56:09; author: perex; state: Exp; lines: +2 -2
Sync with the kernel tree
This patch restores the old code for 2.4.x kernels (tested and known to
work with my kernel only):
