This have changed as the driver grew support for later hardware generations and the callback is now expected to setup links for all VIN in the group. The argument to the callback have however remained a pointer to a single VIN instance. This pointer was then used to get the group structure. Fix this and pass the group as the single argument to the link setup callback making the expectation of the function clear. There is no intentional change in behavior.

All work is already done as this is already supported on Gen3, and later. All that is missing is some small touch ups of the unified v4l-notifier, unconditionally creation of a media pad for each VIN and removing all special cases for the non media-graph call paths. Mark the completion of converting from soc_camera by injecting an attribution of myself in the header.
