[PATCH] drivers: most: replace snprintf in show functions with sysfs_emit

From: cgel . zte

From: Jing Yao <yao.jing2@xxxxxxxxxx>

coccicheck complains about the use of snprintf() in sysfs show
funcitons:
WARNING use scnprintf or sprintf

Use sysfs_emit instead of scnprintf, snprintf or sprintf makes more
sense.
