Subject: [PATCH v3 20/25] powerpc: Use do_kernel_power_off()
Date: Mon, 8 Nov 2021 03:45:19 +0300 [thread overview]
Message-ID: <20211108004524.29465-21-digetx@gmail.com> (raw)
In-Reply-To: <20211108004524.29465-1-digetx@gmail.com>
Kernel now supports chained power-off handlers. Use do_kernel_power_off()
that invokes chained power-off handlers. It also invokes legacy
pm_power_off() for now, which will be removed once all drivers will
be converted to the new power-off API.
