Subject: gpio_free might sleep, mips architecture
From: Uwe Kleine-König <ukleinek@xxxxxxxxxxxxxxxxxxxxxxxxxx>
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 mips
architecture.
