Subject: [PATCH 3/7] s390/qeth: Convert snprintf() to scnprintf()

From: Jules Irenge <[email-masked]>
Date: Mon, 26 Sep 2022 19:42:38 +0100

Coccinnelle reports a warning
Warning: Use scnprintf or sprintf
Adding to that, there has been a slow migration from snprintf to scnprintf.
This LWN article explains the rationale for this change
https: //lwn.net/Articles/69419/
Ie. snprintf() returns what *would* be the resulting length,
while scnprintf() returns the actual length.
