From 0df1a41f62544ed631e768cbda46d19db4f74de1 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 21 Sep 2020 17:52:51 +0100 Subject: libfdt: fdt_mem_rsv(): Fix comparison warnings With -Wsign-compare, compilers warn about a mismatching signedness in comparisons in fdt_mem_rsv(). Since all involved values must be positive, change the used types to be unsigned.
