From 68876c38c4b30653c1779414954ce747a455253c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 11 Apr 2021 04:45:30 +0900 Subject: kconfig: mconf,nconf: remove unneeded '\0' termination after snprintf() snprintf() always terminates the destination buffer with '\0' even if the buffer is not long enough. (In this case, the last element of the buffer becomes '\0'.) The explicit termination is unneeded.
