Subject: [PATCH v5 05/18] platform: chrome: cros_ec: Do not attempt to register a non-positive IRQ number
Date: Fri, 15 Nov 2019 01:33:59 -0800	[thread overview]
Message-ID: <20191115093412.144922-6-gwendal@chromium.org> (raw)
In-Reply-To: <20191115093412.144922-1-gwendal@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.
