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

2026-07-13T00:34:41Z

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. Assisted-by: Claude:claude-sonnet-5 Signed-off-by: Babanpreet Singh Signed-off-by: Jonathan Cameron

Merge tag 'v7.2-rc2' into togreg

2026-07-06T15:59:47Z

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)

2026-07-03T05:38:17Z

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

2026-07-02T15:43:51Z

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. Signed-off-by: Xiaofeng Yuan Signed-off-by: Jonathan Cameron

staging: iio: Initialize spi_device_id arrays using member names

2026-06-30T22:58:53Z

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

2026-06-29T23:15:56Z

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. This patch doesn't modify the compiled arrays, only their representation in source form benefits.

staging: iio: ad9834: use dev_err_probe() in probe function

2026-05-31T09:59:33Z

Replace open-coded dev_err() + return sequences with dev_err_probe(), which is the preferred pattern for probe error paths as it handles deferred probing correctly and reduces boilerplate. Convert all three remaining instances in ad9834_probe(): - master clock enable failure - device init SPI sync failure The avdd regulator path already used dev_err_probe().

Refactor the ad9832_calc_freqreg by removing the redundant u64 casts and 1L bitwise left shift and replacing the multiplication by a bit shift, as multiplying integers by a power of two is identical to a bitwise left shift.
