The camera's pinctrl configuration is simply empty and not effective.
Remove it to fix dtbs_check warning:

   arch/arm/boot/dts/exynos4412-odroidx.dt.yaml: camera: pinctrl-0: True is not of type 'array'

I think that this was intentional to properly enable support for
mem-2-mem mode in Exynos4-IS (FIMC), but I'm not sure what are the
default values if no pinctrl properties are provided. Sylwester, could
you comment?

Indeed it could be intentional... I see now errors:
[   33.752203] s5p-fimc-md soc:camera: Failed to get pinctrl: -19

I wonder why getting an empty pinctrl is needed... maybe the driver
should accept missing pinctrl?

Best regards,
Krzysztof
