mac80211: copy chandef from AP vif to VLANs
Instead of keeping track of all those special cases where VLAN interfaces have no bss_conf.chandef, just make sure they have the same as the AP interface they belong to. Among others, this fixes a crash getting a VLAN's channel from userspace since a NULL channel is returned as a good result (return value 0) for VLANs since the commit below. Cc: stable@vger.kernel.org [3.18 only] Fixes: c12bc4885f4b3 ("mac80211: return the vif's chandef in ieee80211_cfg_get_channel()") Signed-off-by: Felix Fietkau <nbd@openwrt.org> [rewrite commit log] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
