From fc4e78481afa33585195e896f0f9d9cec1129c80 Mon Sep 17 00:00:00 2001 From: Ye Guojin Date: Thu, 21 Oct 2021 11:06:08 +0000 Subject: char: ipmi: replace snprintf in show functions with sysfs_emit coccicheck complains about the use of snprintf() in sysfs show functions: WARNING use scnprintf or sprintf Use sysfs_emit instead of scnprintf, snprintf or sprintf makes more sense.
