Subject: [PATCH 4/6] s390: simplify one level sysctl registration for cmm_table
Date:   Fri, 10 Mar 2023 15:45:23 -0800

Precedence: bulk

There is no need to declare an extra tables to just create directory,
this can be easily be done with a prefix path with register_sysctl().

Simplify this registration.
