This was missing until now and the underlying
_regulator_do_set_voltage is using this value when calling list_voltage.

Commit 4dbd8f63f07a (regulator: gpio-regulator: Set the smallest
voltage/current in the specified range) forgot to set the newly
introduced best_val.

Therefore it stayed always at INT_MAX thus breaking the setting
of the voltage.

Included is also an init value for target, as warnings about
a possibly uninitialised target started appearing with this fix.

The devm_kzalloc function eliminates the need for manual resource releasing
and simplify error handling. Resources allocated by devm_* are freed
automatically on driver detach.

Thus adding kfree calls here will introduce double free bug.

The memory of desc array and the pointers to the rdev[] are allocated by
devm_kzalloc call for struct palmas_pmic.

struct palmas_pmic {
        struct palmas *palmas;
        struct device *dev;
        struct regulator_desc desc[PALMAS_NUM_REGS];
        struct regulator_dev *rdev[PALMAS_NUM_REGS];
        struct mutex mutex;

        int smps123;
        int smps457;

        int range[PALMAS_REG_SMPS10];
};

Which means we should not call kfree for pmic->rdev and pmic->desc.

Pull MFD changes from Samuel Ortiz:
 "Besides the usual cleanups, this one brings:

   * Support for 5 new chipsets: Intel's ICH LPC and SCH Centerton,
     ST-E's STAX211, Samsung's MAX77693 and TI's LM3533.

   * Device tree support for the twl6040, tps65910, da9502 and ab8500
     drivers.

   * Fairly big tps56910, ab8500 and db8500 updates.

   * i2c support for mc13xxx.

   * Our regular update for the wm8xxx driver from Mark."

Fix up various conflicts with other trees, largely due to ab5500 removal
etc.

Pull regulator updates from Mark Brown:
 "The major thing here is the addition of some helpers to factor code
  out of drivers, making a fair proportion of regulators much more just
  data rather than code which is nice.

  - Helpers in the core for regulators using regmap, providing generic
    implementations of the enable and voltage selection operations which
    just need data to describe them in the drivers.
  - Split out voltage mapping and voltage setting, allowing many more
    drivers to take advantage of the infrastructure for selectors.
  - Loads and loads of cleanups from Axel Lin once again, including many
    changes to take advantage of the above new framework features
  - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI
    TPS65913, TI TWL6035 and TI TWL6037.

  Some of the registration changes to support the core refactoring
  caused so many conflicts that eventually topic branches were abandoned
  for this release."
