Subject: [PATCH 01/12] gpio: Use unsigned int for interrupt numbers
Date: Mon, 3 Apr 2017 18:05:21 +0200 [thread overview]
Message-ID: <20170403160532.20282-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20170403160532.20282-1-thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
Interrupt numbers are never negative, zero serves as the special invalid
value.
