Prototype was for __v4l2_async_notifier_add_fwnode_subdev() instead include/media/v4l2-async.h:207: warning: expecting prototype for v4l2_async_notifier_add_fwnode_remote_subdev(). Prototype was for __v4l2_async_notifier_add_fwnode_remote_subdev() instead include/media/v4l2-async.h:230: warning: expecting prototype for v4l2_async_notifier_add_i2c_subdev(). Prototype was for __v4l2_async_notifier_add_i2c_subdev() instead Maybe introduced by commit c1cc23625062 ("media: v4l2-async: Discourage use of v4l2_async_notifier_add_subdev") -- Cheers, Stephen Rothwell
