staging: iio: adt7316: Remove redundant dev_err()

2026-07-24T00:14:07+00:00

Since commit
55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"),
devm_request_threaded_irq() automatically logs detailed error messages
on failure. Remove the now-redundant driver-specific dev_err() calls.

staging: iio: frequency: remove incorrect kernel-doc markings in dds.h

2026-07-13T00:34:41+00:00

The 13 comment blocks in dds.h noting which sysfs attribute each
convenience macro creates are opened with the kernel-doc /** marker,
but they are not kernel-doc: there is no identifier to document.
Running kernel-doc on the file emits 103 warnings:

  $ scripts/kernel-doc -none drivers/staging/iio/frequency/dds.h
  Warning: drivers/staging/iio/frequency/dds.h:10 Cannot find
  identifier on line:
   * /sys/bus/iio/devices/.../out_altvoltageX_frequencyY

The header is not scanned during normal builds (build-time kernel-doc
checks cover .c files), so the warnings only show up when kernel-doc
is invoked on the file directly.

The comments have carried the /** marker since the file was introduced
in commit 4851d97d87c8 ("Staging: IIO: dds.h convenience macros"). The
attributes themselves are already documented in
drivers/staging/iio/Documentation/sysfs-bus-iio-dds, so demote the
comments to plain /* style rather than converting them into kernel-doc
for the macros. No functional change.

Merge tag 'v7.2-rc2' into togreg

2026-07-06T15:59:47+00:00

Linux 7.2-rc2

Done to resolve conflicts with header reorg around mod_devicetable.h
and provide a base for other inflight series that touch the includes.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of  by the more specific
 where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

staging: iio: frequency: reorder dds.h macro parameters to match IIO convention

2026-07-02T15:43:51+00:00

The IIO subsystem convention requires that the file permission
(_mode) parameter be the first argument of IIO_DEV_ATTR_* macros.
The dds.h macros had _mode after _channel, causing checkpatch to
misinterpret the channel number as a permission value.

Reorder the parameters so _mode is first, matching the convention
established by IIO_DEV_ATTR_SAMP_FREQ in include/linux/iio/sysfs.h.
Where _mode is hard coded, make it a parameter in the interests
of consistency and update all callers to match previously hard coded
value.

Update all callers in ad9834.c and ad9832.c accordingly.

Compile tested.

staging: iio: Initialize spi_device_id arrays using member names

2026-06-30T22:58:53+00:00

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
spi_device_id that replaces .driver_data by an anonymous union.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

staging: iio: Drop unused assignment of spi_device_id driver data

2026-06-29T23:15:56+00:00

The drivers explicitly set the .driver_data member of struct
spi_device_id to zero without relying on that value. Drop these unused
assignments.

While touching these arrays use named initializers for .name.

in source form benefits. The former was confirmed with x86 and arm64

staging: iio: addac: adt7316: document SPI interface switching sequence

2026-05-31T09:59:40+00:00

The device powers up in I2C mode. Switching to SPI mode
requires sending a sequence of SPI writes as described in
the datasheet.

During this sequence, the device may still be in I2C mode,
so SPI transactions may not be recognized and can fail.
Such errors are therefore ignored.

Add a comment to clarify this behavior.
