ACPI: video: Adjust event notification routine
Adjust acpi_video_bus_notify() to cast its "data" argument to a struct
acpi_video_bus 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.
