[yocto] [meta-raspberrypi][PATCH v5 3/4] linux-raspberrypi-base.bbclass: support for .dtbo files for dtb overlays

[Francois Muller]

Hi Hervé,
I haven't tested your patch yet, but while reviewing the diff I'm a
bit surprised about this:
>          overlays = oe.utils.str_filter_out('\S+\-overlay\.dtb$', > dts
, d)
> +        overlays = oe.utils.str_filter_out('\S+\.dtbo$', > overlays,
> d)
Shouldn't .dtbo files be filtered out from 'dts' instead of 'overlays'
in the added line?
Seems like a typo to me.
BR,
François
