Since
commit 86d37bf31af6 ("media: i2c: max9286: Allocate v4l2_async_subdev dynamically")
the async subdevice registered to the max9286 notifier is dynamically
allocated by the v4l2 framework by using the
v4l2_async_notifier_add_fwnode_subdev() function. In order to allocate
enough space for max9286_asd structure that encloses the async subdevice
paired with a pointer to the corresponding source, pass to the framework
the size of the whole structure in place of the one of the enclosed async
subdev.
