coccicheck complains about the use of snprintf() in sysfs show functions. Fix the following coccicheck warning: drivers/char/hw_random/s390-trng.c:114:8-16: WARNING: use scnprintf or sprintf. drivers/char/hw_random/s390-trng.c:122:8-16: WARNING: use scnprintf or sprintf. Use sysfs_emit instead of scnprintf or sprintf makes more sense.
