[Bug 212960] Re: Hardy: cx88 NULL pointer dereference

[Frank Haverkamp]

Hi Stefan,

for me I think I can say relatively sure that it is a locking problem of the 
list data structures. I added printouts to to point where the list is modified. 
Putting the mutex around all spots with list modification helped for me:
+
+       mutex_lock(&register_mutex);
        list_add(&dev->list, &card->devices);   /* add to the head of list */
+       mutex_unlock(&register_mutex);
        return 0;

As Tim already said, it might not be the ultimate fix, but I think it is
at least in the right direction. Has somebody contact to the alsa
developers? If so what do they say?

What is your proposed fix doing? Can you point me at the change e.g. the
patch?

Thanks,

Frank
