[PATCH 5.15 068/206] bus: sunxi-rsb: Remove the shutdown callback

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Samuel Holland <samuel@xxxxxxxxxxxx>

[ Upstream commit 5f4696ddca4b8a0bbbc36bd46829f97aab5a4552 ]

Shutting down the RSB controller prevents communicating with a PMIC
inside pm_power_off(), since that gets called after device_shutdown(),
so it breaks system poweroff on some boards.
