[PATCH AUTOSEL 6.6 071/139] selftests/nolibc: avoid passing NULL to printf("%s")

by Sasha Levin

From: Thomas Weißschuh <linux(a)weissschuh.net> [ Upstream commit f1a58f61d88642ae1e6e97e9d72d73bc70a93cb8 ] Clang on higher optimization levels detects that NULL is passed to printf("%s") and warns about it.
