From b6c2e77d34ff775e4cf4ca803877dafd74737551 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 9 Jun 2017 13:41:27 +0200 Subject: gpio: mockup: refuse to accept an odd number of GPIO ranges 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.
