This will not work if a usb device is also connected. It will have 3 video nodes and the logic used here will then not work.

Seems to be enough, but could you please add here how would the busnum look like for each of the mipi devices, for example if 2 devices are connected?
Besides that, if this is chosen as unique_id, the above comment can be removed.

Thank you.
Below is an example of busnum as well as the card param: [bus_info -- card_info] of 4 x D457 mipi devices. Bus_info seems to be unique to each mipi device and work in current system.
