2024-01-23iio: accel: da280: Stop using ACPI_PTR()Jonathan Cameron
In general using ACPI_PTR() leads to more fragile code for a very minor saving in storage in the case of !CONFIG_ACPI so in IIO we prefer not to use it if the only ACPI specific code is the acpi_device_id table. In this case will also suppress a unused variable warning.

2024-01-22iio: accel: da280: Simplify id-matchingHans de Goede
da280_match_acpi_device() is a DIY version of acpi_device_get_match_data(), so it can be dropped. And things can be simplified further by using i2c_get_match_data() which will also check i2c_client_id style ids.

2023-05-21iio: Switch i2c drivers back to use .probe()Uwe Kleine-König
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.

2022-02-18iio:accel:da280: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etcJonathan Cameron
Letting the compiler remove these functions when the kernel is built without CONFIG_PM_SLEEP support is simpler and less error prone than the use of #ifdef based config guards. Removing instances of this approach from IIO also stops them being copied into new drivers.

2021-07-17iio: accel: da280: convert probe to device-managed functionsAlexandru Ardelean
This is another simple conversion to device-managed functions, requiring the use of devm_iio_device_register() and moving the disabling of the device on a devm_add_action_or_reset() hook. The i2c_set_clientdata() can be removed, as the PM functions can work with just the device object, to obtain the i2c_client object.

2021-03-25iio: Remove kernel-doc keyword in file header commentGwendal Grignou
Remove kernel-doc keyword from function header comment. It fixes issues spotted by scripts/kernel-doc like: drivers/iio/<driver>.c:3: info: Scanning doc for function <component name> drivers/iio/<driver>.c:X: warning: expecting prototype for <component name>. Prototype was for <function>() instead To reproduce the errors: scripts/kernel-doc -v -none $(find drivers/iio/ -name \*.c \ -exec head -2 {} \+ | grep -B2 -e '\*\*' | grep '==' | cut -d ' ' -f 2) After, confirm these errors are gone with: scripts/kernel-doc -v -none $(git show --name-only | grep -e "^driver") Signed-off-by: Gwendal Grignou <gwendal@chromium.org> Link: https://lore.kernel.org/r/20210309234314.2208256-1-gwendal@chromium.org Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean
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.
