[PATCH] utsname: simplify one-level sysctl registration for uts_kern_table

[Luis Chamberlain <mcgrof@kernel.org>]

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.

This is part of the effort to phase out calls that can recurse from
sysctl registration [0]. If you have a tree to take this in feel free
to take it, or I can take it too through sysclt-next. Let me know!

This file has no explicit maintainer, so I assume there is no tree.

If I so no one taking it I can take in as part of sysctl-next later.
