From 1dde0d57a5d1281aaa949e9bf7b5c476345a56ee Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Fri, 31 Aug 2018 21:31:26 +0200 Subject: efi_loader: rename utf16_strlen, utf16_strnlen The function names utf16_strlen() and utf16_strnlen() are misnomers. The functions do not count utf-16 characters but non-zero words. So let's rename them to u16_strlen and u16_strnlen(). In utf16_dup() avoid assignment in if clause.
