Right. That should not be an issue for you right now. The driver does not
seem to get to a state where that would matter.
So taking a look at brcmf_ops_sdio_probe() [1]. It should end up calling
brcmf_sdiod_probe() which would show up in the kernel log. As it doesn't I
only see two places that may fail but those are allocations so that would
dump a stack trace in the log. So I have no clue unless that SDK you are
using has some modifications in brcmfmac driver.
Regards,
Arend
