Subject: [PATCH v2 0/2] netpoll: Cleanup netpoll locking and sparse warnings

I was fixing some sparse warnings in netpoll from a previous commit, and it was
pointed out to me that one of the rcu_dereferences that I fixed up in 
__netpoll_cleanup might not have been correct.  On investigation I found that 
rtnl_dereference should have been the correct macro to use, but we had a path in
which we weren't properly holding the rtnl lock.  This patch series fixes up the
locking in the __netpoll_free_rcu path, and then properly corrects the sparse 
warnings in the netpoll.c file that I previously introduced.
