Subject: 3.10-rc: bluetooth disappeared on thinkpad x60 (regression)

Hi!

>From start of 3.10-rc series, bluetooth seems to be gone on thinkpad
x60.

root@amd:~# uname -a
Linux amd 3.10.0-rc5+ #261 SMP Mon Jun 10 02:59:55 CEST 2013 i686

Can't init device hci0: Operation not supported (95)
root@amd:~# hcitool inq
Inquiring ...
Inquiry failed.: No such device
root@amd:~# 

(This is regression from 3.9.)

dmesg does not show much:

thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked
thinkpad_acpi: warning: userspace override of important firmware LEDs
is enabled
thinkpad_acpi: Standard ACPI backlight interface available, not
loading native one
thinkpad_acpi: volume: disabled as there is no ALSA support in this
kernel

Bluetooth LED is on (and wifi works), so it is not hardware kill
switch.
