Subject: Re: [power] 47b918cf9a: kmsg.power_supply_ADP1:Error_in_uevent_for_wakeup_sysfs_add

This version of the patch was not merged and the message above doesn't
exist in the merged patch:
https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/commit/?h=bleeding-edge&id=9a3e9e6ff6d7f6b8ce7903893962d50adcbe82d2

The err log was emitted during boot as well and is innocuous since the
power_supply initializes fully in the next line:
kern  :err   : [    5.918034] power_supply ADP1: Error in uevent for
wakeup_sysfs_add: -11
kern  :info  : [    5.918300] ACPI: AC Adapter [ADP1] (on-line)
