{cfg,mac}80211.h: fix some kernel-doc warnings
When building the 80211 DocBook, scripts/kernel-doc reports the following type of warnings: Warning(include/net/cfg80211.h:334): No description found for return value of 'cfg80211_get_chandef_type' These warnings are only reported when scripts/kernel-doc runs in verbose mode. To fix these use "Return:" to describe function return values. Signed-off-by: Yacine Belkadi <yacine.belkadi.1@gmail.com> [adjust for freq_reg_info() change] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
