Subject: [PATCH net-next 1/4] s390/lcs: Convert sysfs sprintf to sysfs_emit

From: Alexandra Winter <[email-masked]>
Date: Tue, 20 Jun 2023 10:34:08 +0200

From: Thorsten Winkler <[email-masked]>

Following the advice of the Documentation/filesystems/sysfs.rst.
All sysfs related show()-functions should only use sysfs_emit() or
sysfs_emit_at() when formatting the value to be returned to user space.

While at it, follow Linux kernel coding style and unify indentation
