From: Hans de Goede <hdegoede@xxxxxxxxxx>
commit ff4c4a2a4437a6d03787c7aafb2617f20c3ef45f upstream.
Move the bq27xxx_battery_update() functions to below
the bq27xxx_battery_current_and_status() function.
This is just moving a block of text, no functional changes.
This is a preparation patch for making bq27xxx_battery_update() check
the status and have it call power_supply_changed() on status changes.
Fixes: 297a533b3e62 ("bq27x00: Cache battery registers")
