Currently we use two different naming schemes in the IIO API, iio_verb_object
and iio_object_verb. E.g iio_device_register and iio_allocate_device. This
patches renames instances of the later to the former. The patch also renames allocate to
alloc as this seems to be the preferred form throughout the kernel.
In particular the following renames are performed by the patch:
iio_put_device -> iio_device_put
iio_allocate_device -> iio_device_alloc
iio_free_device -> iio_device_free
iio_get_trigger -> iio_trigger_get
iio_put_trigger -> iio_trigger_put
iio_allocate_trigger -> iio_trigger_alloc
iio_free_trigger -> iio_trigger_free
The conversion was done with the following coccinelle patch with manual fixes to
comments and documentation.

MODULE_ALIAS due to using MODULE_DEVICE_TABLE instead).

In the adis16220_write_16bit() function we used a long value to store
parsed data from the char* buffer buf.
The called function to actually write the data,
adis16220_spi_write_reg_16(), takes a u16 value as a parameter, so up
to now a value larger than u16 was silently ignored as it was only
truncated when passing the parameter.
Now this function will only accept values fitting into a u16.
Additionally the parsing function was changed to overcome the now
obsolete strict_strtol() function.

Quite a few iio drivers provide no MODULE_DEVICE_TABLE or MODULE_ALIAS or only
provide a MODULE_ALIAS while they have support for multiple device ids. This
prevents auto module loading from working correctly.
This patch fixes it by adding the missing MODULE_DEVICE_TABLEs and
MODULE_ALIAS'.

Internally the fact that say scale is shared across channels is
actually of remarkably little interest. Hence lets not store it.
Numerous devices have weird combinations of channels sharing
scale anyway so it is not as though this was really telling
us much. Note however that we do still use the shared sysfs
attrs thus massively reducing the number of attrs in complex
drivers.
Side effect is that certain drivers that were abusing this
(mostly my work) needed to do a few more checks on what the
channel they are being queried on actually is.
This is also helpful for in kernel interfaces where we
just want to query the scale and don't care whether it
is shared with other channels or not.

Currently the iio framework uses bitmasks for the address field of channel info
attributes. This is for historical reasons and no longer required since it will
only ever query a single info attribute at once. This patch changes the code to
use the non-shifted iio_chan_info_enum values for the info attribute address.

Fix a dumb lack of consideration of the effect of combining
the iio_device_unregister and iio_free_device calls into
one. There is no valid place to free some of the sysfs
array elements.

I still have numerous issues with this driver and it
needs a substantial rewrite.
Whilst doing this patch at least one bug has been fixed (temp
reading didn't have an address) and a number of missing channel
info elements added.
Untested!

Suggested by Arnd Bergmann. Note this will break ALL drivers that
are out of mainline. The fix is trivial change of
iio_allocate_device() -> iio_allocate_device(0)

These drivers use kzalloc() but don't include slab.h. They currently
build though because the spi.h header will pull in slab.h for us. But
rather than rely on that behavior forever, include slab.h explicitly.
