All error/warnings:
net/mac80211/tx.c: In function 'ieee80211_subif_start_xmit':
net/mac80211/tx.c:1930:21: warning: 'chanctx_conf' may be used uninitialized in this function [-Wmaybe-uninitialized]
It's conditionally assigned to in this chunk:
case NL80211_IFTYPE_AP:
fc |= cpu_to_le16(IEEE80211_FCTL_FROMDS);
/* DA BSSID SA */
memcpy(hdr.addr1, skb->data, ETH_ALEN);
memcpy(hdr.addr2, sdata->vif.addr, ETH_ALEN);
memcpy(hdr.addr3, skb->data + ETH_ALEN, ETH_ALEN);
hdrlen = 24;
+ if (sdata->vif.type == NL80211_IFTYPE_AP)
+ chanctx_conf = rcu_dereference(sdata->vif.chanctx_conf);
break;
