Subject[PATCH 4.18 065/123] lib/vsprintf: Do not handle %pO[^F] as %px
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Van Assche <bart.vanassche@wdc.com>

commit 554ec508653688c21d9b8024af73a1ffaa0164b9 upstream.

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]) {
^~~~~~

Fixes: 7b1924a1d930eb2 ("vsprintf: add printk specifier %px")
