Alexander A. Klimov 3593cd5396 Replace HTTP links with HTTPS ones: drivers/iio
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

Jonathan Cameron 0896ffdd83 iio:adc:ti-adc0832: drop CONFIG_OF and of_match_ptr protections
These just prevent the driver being used with ACPI PRP0001.

I am also trying to remove these from IIO in general to avoid
them being coppied into new drivers.

Also include the mod_devicetable.h header as we are using
of_device_id which is defined in there.

Lars-Peter Clausen 8cb631ccbb iio: Remove superfluous of_node assignments
If a driver does not assign an of_node to a IIO device to IIO core will
automatically assign the of_node of the parent device. This automatic
assignment is done in the iio_device_register() function.

There is a fair amount of drivers that currently manually assign the
of_node of the IIO device. All but 4 of them can make use of the automatic
assignment though.

The exceptions are:
 * mxs-lradc-adc: Which uses the of_node of the parent of the parent.
 * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node
   assigned to the IIO device before iio_device_register() is called.

All other drivers are updated to use automatic assignment. This reduces
the amount of boilerplate code involved in setting up the IIO device.

The patch has mostly been auto-generated with the following semantic patch

// <smpl>
@exists@
expression indio_dev;
expression parent;
@@
indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...)
...
-indio_dev->dev.of_node = parent.of_node;

-indio_dev->dev.of_node = parent->of_node;

Alexandru Ardelean d3be83244c iio: remove explicit IIO device parent assignment
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.

Jonathan Cameron 52b31bcc93 iio:adc: drop assign iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made.  The actual structure
elements will shortly go away.
