Subject: [PATCH] bcma: don't fail for bad SPROM CRC

The brcmsmac driver is now checking the bcma SPROM CRCs, leaving some
chipsets unrecognized that were functional prior to the switch. In
particular, the current code bails out on recent Macbooks. This patch
simply ignores the outcome of the CRC check, with the argument that an
unrecognized SPROM should be treated similarly to a non-existing one.

Hi John,

It seems this patch may have gotten lost, at least I have not seen it
on any of the net/wireless parties. Arend, are you ok with the final
wording?

Thanks,
Henrik
