(Originally submitted as 4 patches, "mac80211: change MIMO_PS to SM_PS", "iwlwifi: change MIMO_PS to SM_PS", "ath9k: change MIMO_PS to SM_PS", and "iwlwifi: remove double definition of SM PS". -- JWL) Signed-off-by: Ron Rindjunsky Signed-off-by: Tomas Winkler Signed-off-by: Zhu Yi Signed-off-by: John W.
