Re: [PATCH] Add .set_antenna callback in ath6kl driver to remove wireless core warns

[Prasun Maiti]

Hello Julian,

It was an assumption on my part that the firmware supports a SET
function. I realize it was premature to do so. I am sending another
patch to convert the ath6kl_set_antenna() to a NO-OP. This will take
care of the kernel warning, but would not fire any commands to
firmware. I hope this solution is acceptable.

Thanks,
Prasun
