Subject: [PATCH 1/2] hwmon: (pmbus/max34440): Update adpm12160 coeff due to
 latest FW

adpm12160 is a dc-dc power module. The firmware was updated and the
coeeficients in the pmbus_driver_info needs to be updated. Since the
part has not yet released with older FW, this permanent change to
reflect the latest should be ok.
