[PATCH 10/14] power: supply: axp288_charger: Some minor cleanups

From: Hans de Goede
Date: Sun Dec 18 2016 - 19:09:33 EST


Remove info->health, info->present and info->online caching, as no code
is reading the cached values.

Remove if (changed) check before calling power_supply_changed(), we
return early from axp288_charger_extcon_evt_worker if nothing has
changed, so the check is not needed.
