From 58b4fe7cd59b7a31994bcd441fa9497ebb7d79bc Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Thu, 1 Oct 2020 17:46:28 +0100 Subject: libfdt: libfdt_wip: Fix comparison warning With -Wsign-compare, compilers warn about a mismatching signedness in a comparison in fdt_setprop_inplace_namelen_partial(). fdt_getprop_namelen() will only return negative error values in "proplen" if the return value is NULL. So we can rely on "proplen" being positive in our case and can safely cast it to an unsigned type.
