[lm-sensors] [PATCH] hwmon: (adm1029) Update fan_div cache when writing fan divisor attribute

[Guenter Roeck]

When writing a new value into the fan1_div or fan2_div attribute,
the written value was not copied into the cache. This could result
in reading an old attribute value for up to two seconds after updating
the fan divisor, since values are cached for that long by the driver.
