I used as reference the ath5k Linux device driver and the atheros_hal from
NetBSD. My question is just: can I do this and publish a patch? I am using
the code for myself at the moment and, of course, I would like to share it.
I just don't want to get into troubles.

Here's a dmesg with my patch applied. Note that it adds nothing to the
output so there's not point in publishing the dmesg without the patch.
