Διαβάζοντας εδώ http://ubuntuforums.org/showthread.php?t=2172044 και εδώ http://ubuntuforums.org/showthread.php?t=2103062 δεν έβγαλα και πολύ άκρη..

Συνοπτικά κάνω τα εξής:
1) κατεβάζω απ' εδώ https://www.kernel.org/pub/linux/kernel ... /v3.9-rc4/ το "compat-drivers-3.9-rc4-2-s.tar.bz2"
2) ./scripts/driver-select ath9k
3) make και πέρνω το επόμενο μήνυμα λάθους:

4) ανοίγω το αρχείο "sysfs.c" και προσπαθώ να δω τι γίνεται. Απλή C είναι, δε φαίνεται να έχει κάτι.. Δοκιμάζω να βάλω σε σχόλιο τη γραμμή αλλά παίρνω 30 errors.
Υποθέτω ότι τα warnings μπορούν να αγνοηθούν, γι αυτό αναφέρω το μοναδικό error που είχα.

To επίμαχο σημείο στο αρχείο C είναι αυτό:
