Thanks, confirmed.

With this series applied, the various salvator-xs DTS files are now
throwing up:

    sata: size (19) error for type phandle
    backlight: size (11) error for type phandle

I tried to find out what caused that, but couldn't find it.
Do you have a clue?
Thanks!

Gr{oetje,eeting}s,

                        Geert

when I'm talking to journalists I just say "programmer" or something like that.
