Hi Arned

The use of of_property_read_variable_u32_array was added in
975e6e32215e ("net: dsa: rework switch parsing"). This patch is not in
v4.14. It is in linus/master, so v4.15-rc1 should have it. And the fix
is also in linus/master.

So there does not appear to be anything wrong. I just built v4.14.1
for x86_64 with DSA without problems.
