From ef21e1750158558d8369067e94d02d285011c37e Mon Sep 17 00:00:00 2001 From: Jaejoong Kim Date: Tue, 27 Feb 2018 11:15:59 +0900 Subject: ALSA: Use scnprintf() instead of snprintf() for show The show() method should use scnprintf() not snprintf() because snprintf() may returns a value that exceeds its second argument.
