[PATCH v2 0/6] iio: core: pass parent device as parameter during allocation

Alexandru Ardelean
2020-06-03T11:40:46Z

This patch updates the {devm_}iio_device_alloc() functions to automatically
assign the parent device on allocation.
For iio_device_alloc() this means a new parameter.
For devm_iio_device_alloc() this means a new behavior; the device object is
the parent. For this one, this is the common case for most drivers (except
one: 'lm3533-als').

For the special cases an iio_device_set_parent() has been created to change
the parent betwee allocation & registration.
The purpose of this helper, is mostly to highlight the new behavior of
devm_iio_device_alloc().

This patchset also removes explicit parent assignments from most IIO
drivers (except for lm3533-als).

Using a semantic patch, about 303 drivers are updated, and some needed some
manual attention. This is probably due to some limitations of spatch. At
least in some cases the parent device is not the same variable as passed to
devm_iio_device_alloc(), OR the parent assignment is moved to a separate
function than where devm_iio_device_alloc() is called.

Changelog v1 -> v2:
* added iio_device_set_parent() helper (new commit)
* update commit for lm3533-als to use iio_device_set_parent()
