Hi Dmitry,

There are a few build errors with the example code. It's OK to leave that
as an exercise for the reader. :)

There are a few missing header files, but the biggest build warning/error
is a Section mismatch:
WARNING: modpost: gpio-swnodes: section mismatch in reference: myboard_exit+0x1f (section: .exit.text) -> myboard_swnodes (section: .init.rodata)

so myboard_swnodes should not be marked as __initconst.

cheers.
