Also, I can't see any of the wl1251 drivers from compat-wireless (located in drivers/net/wireless/wl1251) being built at all! Am I missing something? 

No, don't worry.  This is harmless if you don't use WEXT.  Just remove
the CONFIG_CFG80211_WEXT from your .config and the warning should go
away.

Sometimes compat-wireless breaks, when syncing with the latest upstream
sourcers.  If the newest works for you, use that. ;)


> The wl1251 drivers are not built here either - drivers/net/wireless/wl1251 is untouched! Any help or advice as to how can I resolve this would very much appreciated, thanks!

If this is a recent compat-wireless, then the wl1251 driver was moved to
drivers/net/wireless/ti/wl1251.  Can you check that?
