Subject: basic/log: voidify snprintf statements
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=9704e5100d5779b9cf7f6085796c54ef4efbe6a1;p=elogind.git

basic/log: voidify snprintf statements

The buffers are fixed size, so the message may not fit, but we don't
particularly care.
