Another issue.

The "reboot and the /dev/video* devices come up in a completely
different order" problem seems to exist with this version.

The dot graph I supplied previously had "ipu1_csi0 capture" on
/dev/video4.  I've just rebooted, and now I find it's on
/dev/video2 instead.

Here's the extract from the .dot file of the old listing:

        n00000018 [label="ipu1_ic_prpenc capture\n/dev/video0", shape=box, style=filled, fillcolor=yellow]
        n00000021 [label="ipu1_ic_prpvf capture\n/dev/video1", shape=box, style=filled, fillcolor=yellow]
        n0000002e [label="ipu2_ic_prpenc capture\n/dev/video2", shape=box, style=filled, fillcolor=yellow]
        n00000037 [label="ipu2_ic_prpvf capture\n/dev/video3", shape=box, style=filled, fillcolor=yellow]
        n00000048 [label="ipu1_csi0 capture\n/dev/video4", shape=box, style=filled, fillcolor=yellow]
        n00000052 [label="ipu1_csi1 capture\n/dev/video5", shape=box, style=filled, fillcolor=yellow]
        n00000062 [label="ipu2_csi0 capture\n/dev/video6", shape=box, style=filled, fillcolor=yellow]
        n0000006c [label="ipu2_csi1 capture\n/dev/video7", shape=box, style=filled, fillcolor=yellow]

and here's the same after reboot:

        n00000014 [label="ipu1_csi0 capture\n/dev/video2", shape=box, style=filled, fillcolor=yellow]
        n0000001e [label="ipu1_csi1 capture\n/dev/video3", shape=box, style=filled, fillcolor=yellow]
        n00000028 [label="ipu2_csi0 capture\n/dev/video4", shape=box, style=filled, fillcolor=yellow]
        n00000035 [label="ipu1_ic_prpenc capture\n/dev/video5", shape=box, style=filled, fillcolor=yellow]
        n0000003e [label="ipu1_ic_prpvf capture\n/dev/video6", shape=box, style=filled, fillcolor=yellow]
        n0000004c [label="ipu2_csi1 capture\n/dev/video7", shape=box, style=filled, fillcolor=yellow]
        n00000059 [label="ipu2_ic_prpenc capture\n/dev/video8", shape=box, style=filled, fillcolor=yellow]
        n00000062 [label="ipu2_ic_prpvf capture\n/dev/video9", shape=box, style=filled, fillcolor=yellow]

(/dev/video0 and /dev/video1 are taken up by CODA, since I updated the
names of the firmware files, and now CODA initialises... seems the
back-compat filenames don't work, but that's not a problem with imx6
capture.)
