I figured that - since the descriptor locking is going to take some more
time - we should at least start the conversion and protect the GPIO
device list with a mutex.

v2 -> v3:
- move the new sysfs function into gpiolib-sysfs.c

v1 -> v2:
- add a patch renaming two functions
- protect the list in gpio_device_find() too
- coding style tweaks

Bartosz Golaszewski (2):
  gpiolib: rename static functions that are called with the lock taken
  gpiolib: use a mutex to protect the list of GPIO devices
