MLK-11908 mfd: MAX17135: don't free i2c device client
...
i2c device client shouldn't be freed by i2c device driver, there have
problems in below cases:
- one device match to different drivers, the second matched driver will
cannot access i2c device client if it is freed by the first matched
driver.
- one module driver insmod: the first insmod fail free client due to system
low memory, after kswapd system free pages and has enough free pages, the
second insmod will cause match failed.
