Subject: [PATCH v2 3/7] gpio: mockup: refuse to accept an odd number of GPIO ranges
Date: Tue, 30 May 2017 10:58:36 +0200 [thread overview]
Message-ID: <1496134720-5363-4-git-send-email-brgl@bgdev.pl> (raw)
In-Reply-To: <1496134720-5363-1-git-send-email-brgl@bgdev.pl>
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.
