From 26bee335477cf8358a0e5fde19cfc833f83d7633 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 21 Sep 2020 17:53:02 +0100 Subject: libfdt: fdt_node_offset_by_phandle(): Fix comparison warning With -Wsign-compare, compilers warn about a mismatching signedness in a comparison in fdt_node_offset_by_phandle(). Uses a better suited bitwise NOT operator to denote the special value of -1, which automatically results in an unsigned type.
