You cc'ed stable@xxxxxxxxxx so presumably you think it's a pretty
serious bug.

But alas, I (and presumably others) cannot confirm that, because you
didn't describe the bug :( This also means that if someone hits a
problem with this driver, they won't easily be able to work out whether
this patch will fix it.


Under what circumstances does it trigger?

What are the observed effects when it triggers?

Please always include this sort of information when sending bugfixes, thanks.
