this is not a proper fix for this problem. And you only reset the local
host controller. There is no way to send a reset to the remote device.

Did you ever used hcidump and try to find out, why the other side still
things that we are connected. Especially why the local controller things
that we are still connected.

The PS3 remote controller (and the PS3 itself) have special hacked up
version of Bluetooth firmware to play nice with remote wakeup. So it
might simply be an issue with them and it might be better we declare
them broken instead of adding nasty crap in a clean Bluetooth core. Your
patch is nasty crap since I haven't seen any real argument why we should
reset our local controller in that case. It is wild guessing.

Marcel
