Subject: [RFCv1 3/8] mfd: rk808: use syscore for RK808 PMIC shutdown
Date:   Fri,  6 Dec 2019 18:45:31 +0000
Message-Id: <20191206184536.2507-4-linux.amoon@gmail.com>

Precedence: bulk

Use common syscore_shutdown for RK808 PMIC to do
clean I2C shutdown, drop the unused pm_pwroff_fn
function pointers.
