linux-next: manual merge of the net tree with the wireless-currenttree

[Stephen Rothwell]

Hi David,

Today's linux-next merge of the net tree got a conflict in
net/wireless/scan.c between commit
9e81eccf199d910e5ea8db377a43478e4eccd033 ("cfg80211: double free in
__cfg80211_scan_done") from the wireless-current tree and commit
667503ddcb96f3b10211f997fe55907fa7509841 ("cfg80211: fix locking") from
the net tree.

Overlapping additions.  I fixed it up (I think - see below) and can carry
the fix as ncessary.
