So, as I suspected, that means that all write operations fail,
meaning the write operation used by regmap is not supported by
the chip and/or by the i2c controller.

That makes me wonder if the same problem is seen with other variants
of the same problem. If so, we may have to drop regmap support
completely.

Does anyone else of those listening in have a Intel/i801 system
and could possibly test if they have the same problem ?

Thanks,
