OK so I checked this and the problems is these two patches on linux-next:
commit 2f787b0b76bf5de2eaa3ca3a29d89123ae03c856

mac80211: Ensure initializing private mc_list in prepare_multicast().
Fix kernel panic by NULL pointer dereference in the context of
ieee80211_ops->prepare_multicast().
This bug was introduced by commit 22bedad3c.. ("net: convert
multicast list to list_head").
Call __hw_addr_init() in ieee80211_alloc_hw() to initialize
list_head of private device multicast list, like we do in
bond_init().

net: convert multicast list to list_head
Converts the list and the core manipulating with it to be the same
as uc_list.
+uses two functions for adding/removing mc address (normal and "global"
variant) instead of a function parameter.
+removes dev_mcast.c completely.
+exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
manipulation with lists on a sandbox (used in bonding and 80211 drivers)

I don't have time to address this at the moment but reverting it
should do it for you for now. I welcome someone else's patch if they
get to it first.
