Subject: [PATCH] lib/vsprintf: Do not handle %pO[^F] as %px
Date:   Mon,  6 Aug 2018 15:34:21 -0700
Message-Id: <20180806223421.11995-1-bart.vanassche@wdc.com>

This patch avoids that gcc reports the following when building with W=1:

lib/vsprintf.c:1941:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   switch (fmt[1]) {
