Extending the lifetime of the media_device struct is not handled well by the core, as it will erase some data from the struct, when media_device_cleanup() is called after unregistering it. While we have a fixup patch for it already, the usage of those new functions are needed only when we share data with other drivers. So, better to revert the changes.
