Subject: [PATCH 05/13] platform: chrome: cros_ec: Do not attempt to register a non-positive IRQ number
Date: Sun, 22 Sep 2019 10:50:13 -0700	[thread overview]
Message-ID: <20190922175021.53449-6-gwendal@chromium.org> (raw)
In-Reply-To: <20190922175021.53449-1-gwendal@chromium.org>

From: Enrico Granata <egranata@chromium.org>

Add a layer of sanity checking to cros_ec_register against attempting to
register IRQ values that are not strictly greater than 0.
