Subject: [PATCH 09/15] char-misc: Remove the now superfluous sentinel
 element from ctl_table array

From: Joel Granados <j.granados@...sung.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 :
https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/)

Remove sentinel from impi_table and random_table
