3.16.57-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Arnd Bergmann <[email protected]> commit bee92d06157fc39d5d7836a061c7d41289a55797 upstream. gcc-8 warns about some obviously incorrect code: net/mac80211/cfg.c: In function 'cfg80211_beacon_dup': net/mac80211/cfg.c:2896:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict] =46romthe context, I conclude that we want to copy from beacon into new_beacon, as we do in the rest of the function.
