[PATCH 2/3] powerpc/boot: Fix treeboot-currituck CPU node lookup check
From: Thorsten Blum <thorsten.blum@linux.dev>

lkml
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:

fdt_node_offset_by_prop_value() returns a negative error code on
failure - fix the check accordingly.
Fixes: 228d55053397 ("powerpc/47x: Add support for the new IBM currituck platform")
