Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

There is no need to use a per CPU workqueue to poll, especially with the
5s delay used, so allow the scheduler to use any CPU.

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
no-op; interrupt randomness is now collected unconditionally in a very
low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM
flag was scheduled to be removed in 2009 on the
feature-removal-schedule, so this patch is preparation for the final
removal of this flag.

As warned by checkpatch.pl, use #include <linux/gpio.h> instead
of <asm/gpio.h>.

flush_scheduled_work() is deprecated and scheduled to be removed.
* In menelaus, flush menelaus->work directly on probe failure. Also,
make sure the work isn't running on removal.
* In tps65010, cancel_delayed_work() + flush_scheduled_work() ->
cancel_delayed_work_sync(). While at it, remove unnecessary (void)
casts on return value, and use schedule_delayed_work() and
to_delayed_work() instead of using delayed_work's internal work
field.

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.

Fix I2C-drivers which missed setting clientdata to NULL before freeing the
structure it points to. Also fix drivers which do this _after_ the structure
was freed already.

Add function to allow the configuation fo the VDCDC2 register by
external users, to allow changing of the standard and low-power
running modes.
This is needed, for example, for the Simtec IM2440D20 where we need
to use the low-power mode to shutdown the LDO/DCDC that are not needed
during suspend (saving substantial power) and the runtime use of the
low-power mode to change VCore.

If the board does not care where the TPS turns up, then specifiying the
value -1 to get gpiolib to dynamically allocate the base for the chip
is valid.
Change the test to look for != 0, so that any boards specifying zero
will not end up with gpio that they didn't want.

Move the tps65010 driver from drivers/i2c/chips to drivers/mfd
since it's more of a multi-function device than anything else,
and since Jean is trying to vanish drivers/i2c/chips ASAP.
One way to think of these chips are as the PMIC family most
used with OMAP1 generation chips.
