Subject: [PATCH 01/13] scripts/kernel-doc: fix fatal error caused by
cfg80211.h
include/net/cfg80211.h uses __must_check in functions that
have kernel-doc notation. This was confusing scripts/kernel-doc,
so have scripts/kernel-doc ignore "__must_check".
Error(include/net/cfg80211.h:2702): cannot understand prototype: 'struct cfg80211_bss * __must_check cfg80211_inform_bss(...)
