From: Pavan Savoy on 9 Jun 2010 06:30 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.
