Hi!

I thought they stopped working and some ugly bisect would be needed,
but I tried again, and it seems they still work in v4.7:
root@n900:/my/modules# ./run

...which is kind of interesting given the dmesg:
[ 206.219451] Bluetooth: hci0 command 0xfc4c tx timeout
[ 209.219482] nokia_h4p 4806c000.serial: ...sending cmd fc4c len 255
failed -110
[ 209.219543] nokia_h4p 4806c000.serial: Cannot read firmware
[ 209.219573] Bluetooth: hci_setup: something failed, should do the
clean up
[ 219.272918] nokia_h4p 4806c000.serial: Registering HCI H4P device
Patch is attached. Probably contains some unneccessary changes. Config
does not work with video, so you may want to supply working config or
fix it.
So that's the latest version, if you want to play.
