If we do this before wiphy_register +it will result in copying set flags (including IEEE80211_CHAN_DISABLED) +to the orig_flags which is supposed to be persistent. We don't want this +as regulatory change may result in enabling some channels. We shouldn't +mess with orig_flags then (by changing them or ignoring them) so it's +better to just take care of their proper values. + +This patch cleanups code a bit (by taking orig_flags more seriously) and +allows further improvements like disabling really unavailable channels. +We will need that e.g. if some frequencies should be disabled for good +due to hardware setup (design). + +Signed-off-by: Rafał Miłecki <rafal@milecki.pl> +Acked-by: Arend van Spriel <arend.vanspriel@broadcom.com> +Signed-off-by: Kalle Valo <kvalo@codeaurora.org> +--- + +--- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c ++++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c +@@ -6564,8 +6564,7 @@ static int brcmf_setup_wiphy(struct wiph + wiphy->bands[NL80211_BAND_5GHZ] = band; + } + } +- err = brcmf_setup_wiphybands(wiphy); +- return err; ++ return 0; + } + + static s32 brcmf_config_dongle(struct brcmf_cfg80211_info *cfg) +@@ -6930,6 +6929,12 @@ struct brcmf_cfg80211_info *brcmf_cfg802 + goto priv_out; + } + ++ err = brcmf_setup_wiphybands(wiphy); ++ if (err) { ++ brcmf_err("Setting wiphy bands failed (%d)\n", err); ++ goto wiphy_unreg_out; ++ } ++ + /* If cfg80211 didn't disable 40MHz HT CAP in wiphy_register(), + * setup 40MHz in 2GHz band and enable OBSS scanning. + */ |
