Using the sysfs inteface to inspect the pins configuration the system can walk around a path which acquires the same mutex twice. On STiH407 platform, for example : cat /sys/kernel/debug/pinctrl/920f080.pin-controller-front0/pinconf-pins hangs the kernel and never returns. With this patch the mutex is temporary freed.
