Wolfram Sang 7c4509b4cd max17042_battery: Remove obsolete cleanup for clientdata
A few new i2c-drivers came into the kernel which clear the
clientdata-pointer on exit or error. This is obsolete meanwhile,
the core will do it.

MyungJoo Ham 359ab9f5b1 power_supply: Add MAX17042 Fuel Gauge Driver
The MAX17042 is a fuel gauge with an I2C interface for lithium-ion
betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit
registers. Besides, MAX17042 has much more features than MAX17040; e.g.,
a thermistor, current and current accumulation measurement, battery
internal resistance estimate, average values of measurement, and others.

This patch implements a driver for MAX17042.
In this initial release, we have implemented the most basic features of
a fuel gauge: measure the battery capacity and voltage.
