From: Joel Granados <j.granados at samsung.com>

This commit comes at the tail end of a greater effort to remove the
empty elements at the end of the ctl_table arrays (sentinels) which
will reduce the overall build time size of the kernel and run time
memory bloat by ~64 bytes per sentinel (further information Link :

Remove sentinel element from abi_table2. This removal is safe because
register_sysctl implicitly uses ARRAY_SIZE() in addition to checking for
the sentinel.
