Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Fix merge between commit 3adadc08cc1e ("net ax25: Reorder ax25_exit to
remove races") and commit 0ca7a4c87d27 ("net ax25: Simplify and
cleanup the ax25 sysctl handling")
The former moved around the sysctl register/unregister calls, the
later simply removed them.
With help from Stephen Rothwell.
