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.

Do basic address validity checks when a client is being registered. We
already had checks in place for devices which are being detected, but
not for devices which are simply instantiated.
This is a very basic check. We don't want to do strict checking here
because some devices are known to infringe the I2C address constraints
(e.g. IR receivers at 7-bit address 0x7a while this value is
supposedly reserved for 10-bit addresses.) So we assume the caller
knows what it is doing.

Use the same I2C device presence detection code for legacy and new
device detection functions. This is more consistent and makes the code

Since the device we are resuming could be the device containing the
swap device we should ensure that the allocation cannot cause
IO.
On resume, this path is triggered when the running system tries to
continue using its devices. If it cannot then the resume will fail;
to try to avoid this we let it dip into the emergency pools.
The majority of these changes were made when linux-2.6.18-xen.hg
changeset e8b49cfbdac0 was ported upstream in
a144ff09bc52ef3f3684ed23eadc9c7c0e57b3aa but somehow this hunk was
dropped.

Implement ata_scsi_unlock_native_capacity() which will be called
through SCSI layer when block layer notices that partitions on a
device extend beyond the end of the device. It requests EH to unlock
HPA, waits for completion and returns the current device capacity.
This allows libata to unlock HPA on demand instead of having to decide
whether to unlock upfront. Unlocking on demand is safer than
unlocking by upfront because some BIOSes write private data to the
area beyond HPA limit. This was suggested by Ben Hutchings.

area unlocking.
