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.

The lis3l02dq_read_event_config() function returned an ssize_t up to
now, which lead to a compiler warning in line 660 (initialization from
incompatible pointer type). The iio_info struct is defined to accept an
int-returning function as the read_event_config parameter.
Also it seems odd to have the check for (ret < 0) and return ret in
this case, when the return type is signed.

write_frequency
In lis3102dq_write_frequency() we used a long variable to store the
value parsed from the char* buffer buf, as there only was a
strict_strtol() function to parse values.
Now we have got kstrto* which allows us to convert to the right data
type in most cases.
In this particular function we want to write a frequency value, and it
doesn't make sense to allow negative values here (as Dan Carpenter
pointed out in a previous email).
This means we can now parse the value into an unsigned long and get an
error for invalid (e.g. negative) values.

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.

Issue brought up by Lars-Peter Clausen. This is a varient of what
he suggested.
io/iio.h for driver stuff (has to include types.h)
Sub files for the bits drivers may or may not use
iio/sysfs.h
iio/buffer.h (contents of current buffer_generic.h)
(obviously anything offering events will need events.h as well)
iio/types.h for the enums that matter to both
iio_chan_type, iio_modifier
iio/events.h for the event code stuff
IIO_EVENT_CODE and friends. + everything in chrdev.h So this
is the stuff that userspace cares about.
Also include iio_event_type, iio_event_direction
Thus iio drivers include iio.h + as required
events.h
sysfs.h
buffer.h
in kernel users (once that interface is merged) will need inkern.h
which will pull in types.h
Userspace will need just events.h (which pulls in types.h) to get
everything they need to know about. Buffer userspace access doesn't
currently need any core defines. All information about the data
format is passed through sysfs.
