Subject[PATCH] staging: fieldbus: Replace snprintf in show functions with sysfs_emit
Date
From: Jing Yao <yao.jing2@zte.com.cn>

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.
