Subject: [PATCH v2 08/12] power: supply: axp288_charger: Some minor cleanups
Date: Wed, 21 Dec 2016 15:36:53 +0100	[thread overview]
Message-ID: <20161221143657.322-9-hdegoede@redhat.com> (raw)
In-Reply-To: <20161221143657.322-1-hdegoede@redhat.com>

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.
