From f8a2d191cf3a200c080fbf6f8e095589d3afd57f Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 13 Jan 2021 20:29:51 -0700 Subject: [PATCH] uuid: Add a comment for UUID_STR_LEN This macro is the length of the string but excludes the terminator. Users must add 1 when declaring a large-enough string. Add a comment to make this clear.
