[PATCH net-next 2/4] s390/lcs: Convert sprintf to scnprintf

[Alexandra Winter <wintera@linux.ibm.com>]

From: Thorsten Winkler <twinkler@linux.ibm.com>

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.
