Ok should have had the patchset set it per device, and not use the
global poll_interval. Of need to add some logic to see if uses the
global poll_interval or it's own setting.
There are times where you could have multiple batteries connected to
multiple fuel gauges, and want to up the polling interval on certain
ones that are discharging at different rates.
But of course I'll let you guys let me know if this seems useful at all.
