Subject: [V4.0] Regression: Support for Bluetooth Adapter dropped.

Bluetooth has ever been working on my Notebook. I successfully
use Bluetooth mouse and Obex file transfer for years. And with
Kernel V4.00 the Adapter is no longer recognized.

It is an Intel 8087:07da.

The first bad commit is:
commit d0ac9eb72b6dceae318c15ee82ef2aaee233666d

Bluetooth: btusb: Ignore unknown Intel devices with generic descriptor

Can you please revert that commit?

Thanks, J=C3=B6rg

I don't think a revert is necessary. There's already a patch available
that should fix this:

http://marc.info/?l=linux-bluetooth&m=142464845203372&w=2

It should hopefully be making it to 4.0-rc2 or latest 4.0-rc3 (it's in
davem's networking tree at the moment but not yet in Linus's tree).
