The EC/ACPI firmware on Lenovo ThinkPads used to report a status
of "Unknown" when the battery is between the charge start and
charge stop thresholds. On Windows, it reports "Not Charging"
so the quirk has been added to also report correctly.
Now the "status" attribute returns "Not Charging" when
This patch adds the to_power_supply macro to upcast
a device to a power_supply struct.
This is needed because the same piece of code using
container_of is used in various other places, so we
abstract away such low-level operations via a macro.

This is a patch that implements a generic hooking API for the
generic ACPI battery driver.
With this new generic API, drivers can expose platform specific
behaviour via sysfs attributes in /sys/class/power_supply/BATn/
in a generic way.
A perfect example of the need for this API are Lenovo ThinkP
