Follow the advice of the Documentation/filesystems/sysfs.rst
and show() should only use sysfs_emit() or sysfs_emit_at()
when formatting the value to be returned to user space.

Yes, we are working on this. Several patches will come soon, that cleanup whole files.
No need to send additional small patches on this topic at the moment.
