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.
