Subject[PATCH] hwmon: replace snprintf in show functions with sysfs_emit
Date
show() must not use snprintf() when formatting the value to be
returned to user space.

Fix the following coccicheck warning:
drivers/hwmon/smm665.c:378: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
