[libcamera-devel] [PATCH 16/18] libcamera: Add parent argument to constructors of Object-derived classes

[Laurent Pinchart]

Now that the Object class implements parent-child relationships, make it
possible to create EventNotifier and Timer instances with a parent by
adding a parent argument to their constructors.
