[PATCH 24/42] drivers/scsi/hptiop: Convert snprintf to sysfs_emit

From: Li Zhijian
Date: Mon Jan 15 2024 - 23:54:48 EST


Per filesystems/sysfs.rst, show() should only use sysfs_emit()
or sysfs_emit_at() when formatting the value to be returned to user space.

coccinelle complains that there are still a couple of functions that use
snprintf(). Convert them to sysfs_emit().

> ./drivers/scsi/hptiop.c:1114:8-16: WARNING: please use sysfs_emit
> ./drivers/scsi/hptiop.c:1123:8-16: WARNING: please use sysfs_emit

No functional change intended
