From 5d025eb2353550eadbd2fa9b8083a92fe9b07bd9 Mon Sep 17 00:00:00 2001 From: Jukka Laitinen Date: Wed, 19 Jan 2022 11:20:17 +0200 Subject: lib: fix pointer of type 'void *' used in arithmetic Using "void *" in arithmetic causes errors with strict compiler settings: "error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]" Avoid these by calculating on "char *" where 1-byte data size is assumed.
