I'll fix this like so:

mac80211: Fix error introduced in netdev_mc_count() changes.

Commit 4cd24eaf0c6ee7f0242e34ee77ec899f255e66b5
("net: use netdev_mc_count and netdev_mc_empty when appropriate")
added this hunk to net/mac80211/iface.c:

 	__dev_addr_unsync(&local->mc_list, &local->mc_count,
-			  &dev->mc_list, &dev->mc_count);
+			  &dev->mc_list, dev->mc_count);

which is definitely not correct, introduced a warning (reported
by Stephen Rothwell):

net/mac80211/iface.c: In function 'ieee80211_stop':
net/mac80211/iface.c:416: warning: passing argument 4 of '__dev_addr_unsync' makes pointer from integer without a cast
include/linux/netdevice.h:1967: note: expected 'int *' but argument is of type 'int'

and is thus reverted here.
