i2c: Make remove callback return void

The value returned by an i2c driver's remove function is mostly ignored.

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

iio: expose shared parameter in IIO_ENUM_AVAILABLE

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.

iio: remove left-over comments about parent assignment

These were obtained by doing a 'git diff | grep \/\*', in the previous diff
to find comments. These needed a bit more manual review, as the semantic
patch isn't great for catching these.

The result is:
/* Initialize Counter device and driver data */
/* Initialize IIO device */
/* Establish that the iio_dev is a child of the spi device */
/* Estabilish that the iio_dev is a child of the spi device */
/* Initiate the Industrial I/O device */
/* Establish that the iio_dev is a child of the device */
- /* establish that the iio_dev is a child of the i2c device */
- /* establish that the iio_dev is a child of the i2c device */
/* This is only used for removal purposes */
/* setup the industrialio driver allocated elements */
/* variant specific configuration */
/* Setup for userspace synchronous on demand sampling. */
st->readback_delay_us += 5; /* Add tWAIT */
- /* Establish that the iio_dev is a child of the i2c device */
/* Establish that the iio_dev is a child of the i2c device */

Out of which, 4 are really left-over comments about parent assignment.
3 of them are removed by the semantic patch, as the comment removed (by
spatch) would be for an empty line.

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.

drivers: misc: ti_dac7512: Remove duplicate driver

The Texas Instruments DAC7512 has the exact same pinout, programming
interface and power-down modes as the Texas Instruments DAC121S101 and
Analog Devices AD5320, which are already supported by the IIO driver
ad5446.c. Remove the duplicate misc driver.

This requires user space to migrate to the standardized IIO sysfs ABI.
(In other words, it needs to change a filename.)

The IIO driver supports the chip's features more fully, e.g. the ability
to power down the output or choose one of the available powerdown modes.

There is an oddity with the misc driver in that it initializes the SPI
slave to SPI_MODE_0, in contradiction to the datasheet which specifies
that data is latched in on the falling edge, implying that SPI_MODE_1
or SPI_MODE_2 must be used. Another oddity is that Kconfig and the
MODULE_DESCRIPTION() claim the chip has 16-bit resolution although it
actually has 12-bit.
