Details:

snprintf() is being used in linuxgpio.c to convert unsigned GPIO numbers. A
recent commit has changed the format from "%d" to "%ud". "%u" is a valid
conversion specifier, while the trailing 'd' ends up being printed (e.g. '17d'
instead of '17').

This causes GPIO setup to fail:
Can't export GPIO 17, already exported/busy?: Invalid argument

Please replace "%ud" with "%u".
