Steve Longerbeam eae2aed1ea media: v4l2-fwnode: Switch to v4l2_async_notifier_add_subdev ... The fwnode endpoint and reference parsing functions in v4l2-fwnode.c are modified to make use of v4l2_async_notifier_add_subdev(). As a result the notifier->subdevs array is no longer allocated or re-allocated, and by extension the max_subdevs value is also no longer needed. Callers of the fwnode endpoint and reference parsing functions must now first initialize the notifier with a call to v4l2_async_notifier_init(). This includes the function v4l2_async_register_subdev_sensor_common(), and the intel-ipu3, omap3isp, and rcar-vin drivers. Since the notifier->subdevs array is no longer allocated in the fwnode endpoint and reference parsing functions, the callers of those functions must never reference that array, since it is now NULL. Of the drivers that make use of the fwnode/ref parsing, only the intel-ipu3 driver references the ->subdevs[] array, (in the notifier completion callback), so that driver has been modified to iterate through the notifier->asd_list instead.
