From: Adham Abozaeid <adham.abozaeid@xxxxxxxxxxxxx> When killing hostapd, the interface is closed which deinitializes the device, then change virtual interface is called. This change checks if the device is initialized before sending the interface change command to the device Signed-off-by: Adham Abozaeid <adham.abozaeid@xxxxxxxxxxxxx> --- .../staging/wilc1000/wilc_wfi_cfgoperations.c | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) diff --git a/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c b/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c index 9781f712ae3e..66328ac85adc 100644 --- a/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c +++ b/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c @@ -1413,8 +1413,10 @@ static int change_virtual_intf(struct wiphy *wiphy, struct net_device *dev, if (vif->iftype == WILC_AP_MODE || vif->iftype == WILC_GO_MODE) wilc_wfi_deinit_mon_interface(wl, true); vif->iftype = WILC_STATION_MODE; - wilc_set_operation_mode(vif, wilc_get_vif_idx(vif), - WILC_STATION_MODE, vif->idx); + + if (wl->initialized) + wilc_set_operation_mode(vif, wilc_get_vif_idx(vif), + WILC_STATION_MODE, vif->idx); memset(priv->assoc_stainfo.sta_associated_bss, 0, WILC_MAX_NUM_STA * ETH_ALEN); @@ -1426,8 +1428,10 @@ static int change_virtual_intf(struct wiphy *wiphy, struct net_device *dev, priv->wdev.iftype = type; vif->monitor_flag = 0; vif->iftype = WILC_CLIENT_MODE; - wilc_set_operation_mode(vif, wilc_get_vif_idx(vif), - WILC_STATION_MODE, vif->idx); + + if (wl->initialized) + wilc_set_operation_mode(vif, wilc_get_vif_idx(vif), + WILC_STATION_MODE, vif->idx); break; case NL80211_IFTYPE_AP: @@ -1444,8 +1448,10 @@ static int change_virtual_intf(struct wiphy *wiphy, struct net_device *dev, dev->ieee80211_ptr->iftype = type; priv->wdev.iftype = type; vif->iftype = WILC_GO_MODE; - wilc_set_operation_mode(vif, wilc_get_vif_idx(vif), - WILC_AP_MODE, vif->idx); + + if (wl->initialized) + wilc_set_operation_mode(vif, wilc_get_vif_idx(vif), + WILC_AP_MODE, vif->idx); break; default: -- 2.17.1
