Move the conflicting declaration to the end of the structure. Notice that `struct ieee80211_chanctx_conf` is a flexible structure --a structure that contains a flexible-array member. Also, remove a couple of unused structures. Fix the following warnings: drivers/net/wireless/ath/ath11k/core.h:409:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/ath/ath11k/dp.h:1309:24: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/ath/ath11k/dp.h:1368:24: 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.
