x86, debug: gpio_free might sleep
According to the documentation gpio_free should only be called from task context only. To make this more explicit add a might sleep to all implementations. This patch changes the gpio_free implementations for the x86 architecture. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
