[libcamera-devel] [PATCH 3/5] libcamera: media_object: Utilise DELETE_COPY_AND_ASSIGN

[Kieran Bingham]

Convert MediaLink, MediaPad, and MediaEntity to declare DELETE_COPY_AND_ASSIGN.
These classes already deleted their copy constructor but not the assignment operator.

Utilising the DELETE_COPY_AND_ASSIGN prevents all copying of these classes.
