I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

  power_supply: Fix regression for 'type' property

Commit 5f487cd34f4337f9bc27ca19da72a39d1b0a0ab4 (power_supply: Use
attribute groups) causes a regression the power supply core does not
export the 'type' attribute anymore.

POWER_SUPPLY_PROP_TYPE is handled by the power supply core without the
low-level driver, so power_supply_attr_is_visible() must always return
the entry as readable.

For userspace tools and daemons, it might be necessary to adjust
the charge_now and charge_full properties of the ds2760 battery monitor,
for example for unavoidable corrections due to aging batteries.

This patch adds support for writeable power supply properties and
exposes them as writeable to sysfs.

A power supply implementation must implement two new function calls in
order to use that feature:

  int set_property(struct power_supply *psy,
                   enum power_supply_property psp,
                   const union power_supply_propval *val);

  int property_is_writeable(struct power_supply *psy,
                            enum power_supply_property psp);

This fixes a race between power supply device and initial
attributes creation, plus makes it possible to implement
writable properties.

 and dropped .mode attribute from POWER_SUPPLY_ATTR]

Just a handy driver that is used for testing purposes.
