[alsa-devel] [alsa-ucm] segfault at __list_del function in list.h

[sajeesh sidharthan]

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);
}
