Subject: [PATCH v1 08/10] ACPI: battery: Adjust event notification routine

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Adjust acpi_battery_notify() to cast its "data" argument to a struct
acpi_battery pointer instead of a struct acpi_device one, which allows
the use of acpi_driver_data() to be limited and will facilitate
subsequent changes.

No intentional functional impact.
