The shared parameter should be configurable based on its usage, and not
constrained to IIO_SHARED_BY_TYPE.
This patch aims to improve the flexibility in using the
IIO_ENUM_AVAILABLE define and avoid redefining custom iio enums that
expose the shared parameter.
An example is the ad5766.c driver where IIO_ENUM_AVAILABLE_SHARED was
defined in order to achieve `shared` parameter customization.
The current state of the IIO_ENUM_AVAILABLE implementation will imply
similar redefinitions each time a driver will require access to the
`shared` parameter. An example would be admv1013 driver which will
require custom device attribute for the frequency translation modes:
Quadrature I/Q mode and Intermediate Frequency mode.

When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
Using dev_err_probe() can reduce code size, and the error value
gets printed.

Add a device managed hook, via devm_add_action_or_reset() and
max5821_regulator_disable(), to disable voltage regulator on device
detach.
Replace iio_device_register() by devm_iio_device_register() and remove
the max5821_remove() function used to unregister the device and disable the
voltage regulator.
Remove i2c_set_clientdata() from the probe function, since
i2c_get_clientdata() is not used anymore.
Remove regulator_disable() calls from the probe function.

Update DAC drivers powerdown attribute show callback to use the new
sysfs_emit() function.
sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it
knows about the sysfs buffer specifics and has some built-in sanity checks.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

The equivalent of this is now done via macro magic when
the relevant register call is made. The actual structure
element will shortly go away.
