The patch makes properties which return -ENODATA to be ignored when generating uevents. Previously in such a case uevent generation would have been aborted with an error. But since the bq27x00 return -ENODATA for the TIME_TO_FULL property when the battery is not charging and for the TIME_TO_EMPTY property when the battery is not discharging and at least one of them is always true uevent generation would always fail. This series has so far been tested with the bq27000 and the bq27200 battery, but not with the bq27500 battery, so it would be nice if somebody with a board containing such a battery could test the patches to make sure that there are no regressions. Changes since v1: Don't cache registers for fast changing properties like VOLTAGE_NOW, CURRENT_NOW, ENERGY_NOW and CHARGE_NOW which can be obtained by reading only a single register. These were ignored anyway when comparing two battery states and since their register is not shared between different properties we gain nothing by caching them. On the other hand it allows the property to be queried at a higher rate then the caching time.
