Subject: kernel/reboot: Add stub for pm_power_off
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5d34b41aa420c3908793b43419a1097362ca2668;p=linux.git

kernel/reboot: Add stub for pm_power_off

Add weak stub for the global pm_power_off callback variable. This will
allow us to remove pm_power_off definitions from arch/ code and transition
to the new sys-off based API that will replace the global variable.
