[PATCH] scsi: be2iscsi: Use sysfs_emit in show function callback

From: Deepak R Varma
Date: Mon Jan 30 2023 - 14:33:14 EST


According to Documentation/filesystems/sysfs.rst, the show() callback
function of kobject attributes should strictly use sysfs_emit() instead
of sprintf() family functions.
Issue identified using the device_attr_show.cocci Coccinelle script.
