Steve Longerbeam d079f94c90 media: platform: Switch to v4l2_async_notifier_add_subdev ... Switch all media platform drivers to call v4l2_async_notifier_add_subdev() to add asd's to a notifier, in place of referencing the notifier->subdevs[] array. These drivers also must now call v4l2_async_notifier_init() before adding asd's to their notifiers. There may still be cases where a platform driver maintains a list of asd's that is a duplicate of the notifier asd_list, in which case its possible the platform driver list can be removed, and can reference the notifier asd_list instead. One example of where a duplicate list has been removed in this patch is xilinx-vipp.c. If there are such cases remaining, those drivers should be optimized to remove the duplicate platform driver asd lists. None of the changes to the platform drivers in this patch have been tested. Verify that the async subdevices needed by the platform are bound at load time, and that the driver unloads and reloads correctly with no memory leaking of asd objects.
