rfkill switch state during suspend?

[Pavan Savoy <pavan_savoy@yahoo.co.in>]

Hi,

I remember in 2.6.29, the rfkill switch state during suspend was set to SOFT_BLOCKED by calling the toggle_radio of rfkill drivers.

What happens now ? 2.6.32+ ... ?

This previously posed a problems to drivers which mapped their chip enable GPIOs to the rfkill entries, because on suspend, the gpio was pulled low because of the SOFT_BLOCKED state.

A couple of lines regarding same in Documentation/rfkill.txt would be ideal too.

Thanks in advance.
