PMU: battery charge information totally wrong

[Johannes Berg]

Hi,

g-p-m now displays a lot of statistics on the battery so when I looked
at it I noticed that my powerbook is supposed to use less than 2W which
is not quite reasonable :)

The code says:

                /* we don't know the unit here :-/ */
                /*hal_device_property_set_string (d, "battery.charge_level.unit", "percent");*/

Actually, looking at the kernel code and the proc output, it's quite
clear that the unit is mA and mV, so the charge_level.rate would be easy
to calculate as (voltage*amperage)/1000 [mW].
