Subject: hp-wmi: disabling Bluetooth also kills WiFi

Hi!

(I asked before on linux-bluetooth, but I was said hp-wmi developers
didn't hang there... Hope this is the right place.)

With kernels 3.1 and 3.2rc7, disabling Bluetooth via rfkill also disables
my wireless card on my HP Pavilion dm4. This didn't happen with 2.6.41
(I upgraded from Fedora 15 to 16).

My devices are set up as this (see attached output of lspci -vnn for
details about devices):
# rfkill list
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: hp-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
3: hp-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
11: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

The problem is, these commands also stop the WiFi:
rfkill block bluetooth
and
rfkill block 3 [for hp-bluetooth]

But this one only kills the Bluetooth:
rfkill block 11

Running
rfkill block wifi
does kill the WiFi, but leaves the Bluetooth up.

(If it matters, running 'rfkill block bluetooth' makes hci0 disappear,
and after unblocking bluetooth, it reappears with the ID increased by 1.
This doesn't happen with the WiFi.)

Please ask if I can provide more information/testing.

Thanks for your help.

PS : Please keep me in CC: as I'm not subscribed to the list.
