Subject: [PATCH] mfd: rk808: Always use poweroff when requested
Date:   Mon,  9 Dec 2019 12:57:46 +0100
Message-Id: <20191209115746.12953-1-smoch@web.de>
MIME-Version: 1.0
Content-Transfer-Encoding: quoted-printable
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

With the device tree property "rockchip,system-power-controller" we
explicitly request to use this PMIC to power off the system. So always
register our poweroff function, even if some other handler (probably
PSCI poweroff) was registered before.
