The places at atomisp.h that use stddef.h are wrong: the types it needs are actually defined at linux/types.h. Also, it causes lots of smatch warnings due to the redefinition of ofsetof() macro: /opt/gcc-7.1.0/x86/lib/gcc/x86_64-pc-linux-gnu/7.1.0/include/stddef.h:417:9: warning: preprocessor token offsetof redefined ./include/linux/stddef.h:16:9: this was the original definition Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Acked-by: Sakari Ailus <sakari.ailus@iki.fi>

Parse async sub-devices related to the sensor by switching the async sub-device registration function. These types devices aren't directly related to the sensor, but are nevertheless handled by the smiapp driver due to the relationship of these component to the main part of the camera module --- the sensor. This does not yet address providing the user space with information on how to associate the sensor or lens devices but the kernel now has the necessary information to do that.

Registering a notifier has required the knowledge of struct v4l2_device for the reason that sub-devices generally are registered to the v4l2_device (as well as the media device, also available through v4l2_device). This information is not available for sub-device drivers at probe time. What this patch does is that it allows registering notifiers without having v4l2_device around. Instead the sub-device pointer is stored in the notifier. Once the sub-device of the driver that registered the notifier is registered, the notifier will gain the knowledge of the v4l2_device, and the binding of async sub-devices from the sub-device driver's notifier may proceed. The complete callback of the root notifier will be called only when the v4l2_device is available and no notifier has pending sub-devices to bind. No complete callbacks are supported for sub-device notifiers.

The information on how many async sub-devices would be bindable to a notifier is typically dependent on information from platform firmware and it's not driver's business to be aware of that. Many V4L2 main drivers are perfectly usable (and useful) without async sub-devices and so if there aren't any around, just proceed call the notifier's complete callback immediately without registering the notifier itself. If a driver needs to check whether there are async sub-devices available, it can be done by inspecting the notifier's num_subdevs field which tells the number of async sub-devices.

The async subdev notifier .bound(), .unbind() and .complete() operations are function pointers stored directly in the v4l2_async_subdev structure. As the structure isn't immutable, this creates a potential security risk as the function pointers are mutable. To fix this, move the function pointers to a new v4l2_async_subdev_operations structure that can be made const in drivers.

The former iterates over all endpoints whereas the latter only iterates over the endpoints in a given port. The former is mostly useful for existing drivers that currently implement the iteration over all the endpoints themselves whereas the latter is especially intended for devices with both sinks and sources: async sub-devices for external devices connected to the device's sources will have already been set up, or the external sub-devices are part of the master device.

Remove V4L2 async re-probing support. The re-probing support has been there to support cases where the sub-devices require resources provided by the main driver's hardware to function, such as clocks. Reprobing has allowed unbinding and again binding the main driver without explicitly unbinding the sub-device drivers. This is certainly not a common need, and the responsibility will be the user's going forward. An alternative could have been to introduce notifier specific locks. Considering the complexity of the re-probing and that it isn't really a solution to a problem but a workaround, remove re-probing instead. If there is a need to support the clock provider unregister/register cycle while keeping the clock references in the consumers in the future, this should be implemented in the clock framework instead, not in V4L2.

However, 'ARRAY_SIZE(test_pattern_menu) - 1' is actually passed and it's not correct.
