Jetpack 5.1.4
Custom board (with dev board the same behaver)
I get kernel panic when 2 cameras defined in device tree and not connected to the board.
In jetpack 4.6.x everything is fine.
When cameras are connected to the board everything is ok.
When only 1 camera is defined in DT and not connected everything is ok also.
Problem persists only when 2 cameras are defined and not connected.
