I would prefer adding a more generic failure message including ifname
and type in brcmf_cfg80211_add_iface() in cfg80211.c.

Not exactly what I meant. I meant instead of and the function I would
like the error message in is brcmf_cfg80211_add_iface() so you also get
an error message when AP interface creation fails.
