[OpenWrt-Devel] [PATCH v2 19.07 03/12] hostapd: declare struct wpa_bss early

[Petr Štetiar]

From: "Leon M. George" <leon at georgemail.eu>

wps_supplicant.h assumes that 'struct wpa_bss' is forward declared if
CONFIG_WPS is not defined.  With the later inclusion of
600-ubus_support, the issue manifests in warnings like these:

wps_supplicant.h:113:15: warning: 'struct wpa_bss' declared inside parameter list will not be visible outside of this definition or declaration
        struct wpa_bss *bss)
               ^~~~~~~

This patch forward declares 'struct wpa_bss' regardless.
