Subject: [PATCH] message: fusion: replace snprintf in show functions with sysfs_emit
show() must not use snprintf() when formatting the value to be
returned to user space.
Fix the coccicheck warnings:
WARNING: use scnprintf or sprintf.
Use sysfs_emit instead of scnprintf or sprintf makes more sense.
