The default y will kick in only if WL1271_SDIO is selected:

But if we don't select this driver at all, we better have something like:
diff --git a/include/linux/wl12xx.h b/include/linux/wl12xx.h
index 95deae3..51e4ba9 100644
--- a/include/linux/wl12xx.h
+++ b/include/linux/wl12xx.h
@@ -32,7 +32,20 @@ struct wl12xx_platform_data {
int board_ref_clock;
};
+#ifdef CONFIG_WL12XX_PLATFORM_DATA
+
int wl12xx_set_platform_data(const struct wl12xx_platform_data *data);
+
+#else
+
+static inline int wl12xx_set_platform_data(const struct
+ wl12xx_platform_data *data)
+{
+ return -ENOSYS;
+}
+
+#endif
+
const struct wl12xx_platform_data *wl12xx_get_platform_data(void);
#endif
It's better than forcing a select - if we don't need the driver, we
don't need this piece of code too.
I'll give this a spin tomorrow and send it over nicely.

Yes, this one looks good !
Thanks a lot, John.
