Do you mean ssb driver functionality? I remember Michael was fixing
writing some time ago:

    ssb: Fix range check in sprom write

    The range check in the sprom image parser hex2sprom() is broken.
    One sprom word is 4 hex characters.
    This fixes the check and also adds much better sanity checks to the code.
    We better make sure the image is OK by doing some sanity checks to avoid
    bricking the device by accident.

    ssb: Fix SPROM writing

    The SPROM writing routines were broken since we rewrote the suspend
    handling on wireless devices, because SPROM writing depended on suspend.

    This patch changes it and freezes devices with the driver remove(), probe()
    callbacks instead. This also simplifies the whole logics a lot.
