cfg80211: fix cfg80211_beacon_dup
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] From the context, I conclude that we want to copy from beacon into new_beacon, as we do in the rest of the function. Cc: stable@vger.kernel.org Fixes: 73da7d5bab79 ("mac80211: add channel switch command and beacon callbacks") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
