[PATCH] scsi: csiostor: Replace snprintf in show functions with sysfs_emit

From: cgel . zte
Date: Fri Nov 05 2021 - 05:03:33 EST


From: Jing Yao <yao.jing2@xxxxxxxxxx>

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.
