* iio: Switch i2c drivers back to use .probe()Uwe Kleine-König2023-05-211-1/+1
| | | | | | | | | | | | After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

| | | | | | | | | | .probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function.

* iio: remove explicit IIO device parent assignmentAlexandru Ardelean2020-06-141-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-3/+3
| | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* staging:iio: Move DAC drivers out of stagingLars-Peter Clausen2012-06-051-0/+243
The IIO DAC drivers are in a reasonably good shape. They all make use of channel spec and non of them provides non-documented sysfs attributes. Code style should be OK as well, both checkpatch and coccicheck only report trivial issues. So lets move the whole folder out of staging.
