ACPI: glue: Rearrange acpi_device_notify()
Make the code flow in acpi_device_notify() more straightforward and make it use dev_dbg() and acpi_handle_debug() for printing debug messages. The only expected functional impact of this change is the content of the debug messages printed by acpi_device_notify(). Signed-off-by: Rafael J.
