> Missing 'depends on SURFACE_AGGREGATOR' in the Kconfig. Unfortunately, `SURFACE_AGGREGATOR` is what was in the Kconfig, it should have been `SURFACE_AGGREGATOR_BUS` instead, that's where the missing symbol is defined. I wonder if that split still provides value, but that's off topic for this thread. I see that c3747f28ebcefe34d6ea2e4eb2d3bb6b9d574b5f is no longer in the branch, but 42c88a7d1474b6f6e53acca3522d179d3c9b1c6f is where this is already changed over. Thanks again Guenter! ~Ivor
