Subject: [PATCH 5/6] thermal: brcmstb_thermal: Restructure interrupt registration
Date:   Wed, 30 Oct 2019 11:21:31 -0700
Message-Id: <20191030182132.25763-6-f.fainelli@gmail.com>
In-Reply-To: <20191030182132.25763-1-f.fainelli@gmail.com>
References: <20191030182132.25763-1-f.fainelli@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

If we are successful grabbing the interrupt resource, then register an
interrupt handler, this makes it easier to support the interrupt as
being optional, which is it for 7216.
