It must have picked up on the SDIO driver, interesting it only got two
(plus libertas) yet we have 15 SDIO drivers enabled in the kernel.
I'll review the drivers/functions see how it can be evolved. I'll post
a patch of top of this one once confirmed. I've got some other minor
bits to do too.
Thanks,
Peter
