The 'toshiba_acpi_dev' object is allocated first and free'd last. We can bind it's life-time to the parent ACPI device object. This is a first step in using more device-managed allocated functions for this. The main intent is to try to convert the IIO framework to export only device-managed functions (i.e. devm_iio_device_alloc() and devm_iio_device_register()). It's still not 100% sure that this is possible, but for now, this is the process of taking it slowly in that direction.
