Hello.

I am testing pulseaudio ucm. I have faced a crash when active ucm device list empty.

Please let me know if following fix can be checked in alsa-lib-1.0.25/include/list.h

old code:

static __inline__ void list_del(struct list_head *entry) {         __list_del(entry->prev, entry->next); }

new code:

static __inline__ void list_del(struct list_head *entry) {     if(entry->prev && entry->next)         __list_del(entry->prev, entry->next); }
