wifi: cfg80211: annotate iftype_data pointer with sparse
There were are a number of cases in mac80211 and iwlwifi (at least) that used the sband->iftype_data pointer directly, instead of using the accessors to find the right array entry to use. Make sparse warn when such a thing is done. To not have a lot of casts, add two helper functions/macros - ieee80211_set_sband_iftype_data() - for_each_sband_iftype_data() Signed-off-by: Johannes Berg <johannes.berg@intel.com>
