Move the conflicting declaration to the end of the structure and add a code comment. Notice that `struct ieee80211_chanctx_conf` is a flexible structure --a structure that contains a flexible-array member. Fix 50 of the following warnings: net/mac80211/ieee80211_i.h:895:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.
