Subject: [073/197] thinkpad-acpi: log initial state of rfkill switches

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Henrique de Moraes Holschuh <hmh@....eng.br>

commit 5451a923bbdcff6ae665947e120af7238b21a9d2 upstream.

We already log the initial state of the hardware rfkill switch (WLSW),
might as well log the state of the softswitches as well.
