Subject: [PATCH AUTOSEL 4.14 07/87] power: supply: axp288_charger: Fix initial
 constant_charge_current value

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit f2a42595f0865886a2d40524b0e9d15600848670 ]

We should look at val which contains the value read from the register,
not ret which is always 0 on a successful read.
