For this the country code as specified by reg notifier +(iso3166 alpha2) needs to be translated to a device specific +country locale and revision number. This patch adds this +translation and puts a placeholder in the device specific settings +where the translation table can be stored. Additional patches will +be needed to read these tables from for example device platform +data. + +Reviewed-by: Arend Van Spriel <arend@broadcom.com> +Reviewed-by: Franky (Zhenhui) Lin <frankyl@broadcom.com> +Reviewed-by: Pieter-Paul Giesberts <pieterpg@broadcom.com> +Signed-off-by: Hante Meuleman <meuleman@broadcom.com> +Signed-off-by: Arend van Spriel <arend@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 +@@ -6405,28 +6405,85 @@ int brcmf_cfg80211_wait_vif_event(struct + vif_event_equals(event, action), timeout);
