And that commit does not seem relevant for stable backports at all as it
is a new feature. If all you really want to do is fix the "bug", why
not just take half of commit 711f8c3fb3db, i.e. the half that actually
matters in this kernel tree?
Why wouldn't that just work for all of the older kernels? I'll go do
that now as it seems like it will solve the issue, but it would be great
if people could actually test it (hint, why didn't you cc: the bluetooth
developers here?)
