Hi Jon,

I get this error when compiling the latest for_v3.1 media_tree:

Kernel: arch/x86/boot/bzImage is ready  (#400)
ERROR: "vb2_dma_contig_init_ctx"

make[1]: *** [__modpost] Error 1

I think this is missing:

          This is a video4linux2 driver for the Marvell 88ALP01 integrated
          CMOS camera controller.  This is the controller found on first-

Can you confirm this?
