[PATCH v2] scsi: snic: Replace snprintf in show functions with sysfs_emit

From: cgel . zte
Date: Tue Nov 09 2021 - 21:55:37 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.

Changes since v1:
- Revise to meet the format "80 columns".
- Revise to maintain parenthesis alignment.
