Lee, Pavel:

If this is OK for you, can you please provide me with an immutable
branch so that I can pull it into the GPIO tree? It seems it's the
only such use-case in the tree apart from the gpio.h header that I can
fix locally. Alternatively you can just Ack this and let me take it
through the GPIO tree.
