Subject: [PATCH AUTOSEL 6.9 13/44] ACPI: AC: Properly notify powermanagement core about changes
From: Thomas Weißschuh <linux@...ssschuh.net>
[ Upstream commit ac62f52138f752d6c74adc6321e4996d84caf5bb ]
The powermanagement core does various actions when a powersupply changes.
It calls into notifiers, LED triggers, other power supplies and emits an uevent.
To make sure that all these actions happen properly call power_supply_changed().
