Indeed, now that I see this, I can get HDMI audio out, which I couldn't when I
wrote https://bugzilla.kernel.org/show_bug.cgi?id=51421

As long as there is no corruption in the kernel data structures, I prefer to
have HDMI sound and cope with the stack traces instead of the alternative. :)

OK, sent it to Daniel Vetter. Let's see if we can have everything fixed, then.


Thank you all,
