Subject: [PATCH v4 15/25] powerpc: Use do_kernel_power_off()
Date:   Fri, 26 Nov 2021 21:00:51 +0300
Message-Id: <20211126180101.27818-16-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.
