[PATCH 0/2] dm: core: Add address translation in fdt_get_resource - fixes

[Patrick Delaunay]

Hi,

This serie push again 2 modifications proposed in previous serie V3 [1]
but missing in master branch as only patchset V1 [2] is merged.

Simon, I don't add your Reviewed-by, even you sent it for [1].

The first patch solves a issue see by horatiu.vultur at microchip.com
in V1 [2].

Regards,
Patrick

[PATCH 1/2] net: luton: remove address translation after ofnode_read_resource

[Patrick Delaunay]

Removed call of ofnode_translate_address() after ofnode_read_resource
in luton_switch.c:luton_probe(); it is unnecessary since
the commit feb7ac457c20 ("dm: core: Add address translation in
fdt_get_resource").

Fixes: feb7ac457c20 ("dm: core: Add address translation in fdt_get_resource")
