Reported-by: kernel test robot Signed-off-by: Aloka Dixit --- v4: - Modifications to all driver specific function pointers. - Also included all files in a single patch instead of splitting as per the modules because otherwise compilation fails with changes in only net/wireless and include/net directories. drivers/net/wireless/ath/ath6kl/cfg80211.c | 4 +- drivers/net/wireless/ath/wil6210/cfg80211.c | 3 +- .../broadcom/brcm80211/brcmfmac/cfg80211.c | 4 +- .../net/wireless/marvell/mwifiex/cfg80211.c | 3 +- .../wireless/microchip/wilc1000/cfg80211.c | 4 +- .../net/wireless/quantenna/qtnfmac/cfg80211.c | 4 +- include/net/cfg80211.h | 2 +- net/mac80211/cfg.c | 25 +++++++-- net/wireless/nl80211.c | 28 ++++++++-- net/wireless/rdev-ops.h | 2 +- net/wireless/trace.h | 52 +++++++++++-------- 11 files changed, 89 insertions(+), 42 deletions(-) base-commit: 70a5ba4b31aaaba991ba71d248b792e13dc0820e diff --git a/drivers/net/wireless/ath/ath6kl/cfg80211.c b/drivers/net/wireless/ath/ath6kl/cfg80211.c index bd1183830e91..42f289c6d65e 100644 --- a/drivers/net/wireless/ath/ath6kl/cfg80211.c +++ b/drivers/net/wireless/ath/ath6kl/cfg80211.c @@ -2954,7 +2954,7 @@ static int ath6kl_start_ap(struct wiphy *wiphy, struct net_device *dev, } static int ath6kl_change_beacon(struct wiphy *wiphy, struct net_device *dev, - struct cfg80211_beacon_data *beacon) + struct cfg80211_ap_settings *params) { struct ath6kl_vif *vif = netdev_priv(dev);
