I'm sorry, I didn't test your patch yet, but I could capture the output
on the serial console. It doesn't appear to be related to p54 specific
data structures. The driver is initialized correctly. I can bring the
interface up. But once I try scanning, I get a sequence of the
following messages in the kernel log:

That's the current wireless-testing.
If the patch makes any difference, I'll report it separately.
