[PATCH v4 11/13] libcamera: mali-c55: Enable links between resizer and video node

[Daniel Scally]

The mali-c55 driver now expects links to video devices to be enabled
in order for those devices to be streamed from / to. Enable the media
link between the resizers and their associated video device to fulfil
the requirement.
