The referenced commit above is completely unrelated to this failure, as
both CONFIG_SOLO6X10=m and CONFIG_VIDEOBUF2_DMA_SG=m,
while this is about a missing symbol in builtin code.
However, there's something wrong with the VIDEO_CAFE_CCIC dependencies.
Untested gmail-white-space-damaged patch below (so your trick of emailing random
people to obtain a solution worked ;-)
