sorry that I missed that email, I read the subject as FYI if you are
using that driver. Which I actually don't since nobody ever send me
hardware ;)

The patch got merged and is in bluetooth-next-2.6 tree. I normally try
to keep the submission to the changes before the merge window opens. And
then the part that didn't make it at that point will be just scheduled
for the next kernel.

If you guys were ready at least by -rc1, I would have most likely pushed
it to Dave right away, but you weren't. So I just decided that the next
merge window is good enough. Since you guys were not responding timely
to my reviews with an updated patch, I figured it doesn't really matter.
The driver is on its way into Linus' kernel. It will be just 2.6.34 at
this point.

If you feel strongly that the patch needs to go into the current
development kernel, then please mention it somewhere in its submission
to linux-bluetooth. To be honest, once I have it in bluetooth-next-2.6,
the likelihood that I cherry-pick it for the current development kernel
is not that high.

As I said, if Dave is willing to take it, then I cherry-pick it for you
and include it with my next round of fixes.

Regards

Marcel
