[PATCH 06/10] gpio: mockup: refuse to accept an odd number of GPIO ranges

From: Bartosz Golaszewski
Date: Thu May 25 2017 - 04:35:53 EST


Currently we ignore the last odd range value, since each chip is
described by two values. Be more strict and require the user to
pass an even number of ranges.
