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.

iio: resolver: ad2s1210: refactor trigger handler

2026-07-03T19:07:15+00:00

Refactor the trigger handler to avoid use of goto in a guard() scope. Ideally, we should not be mixing goto and automatic cleanup. iio_trigger_notify_done() was not part of the critical section anyway, so is not moved to the new function.

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.

iio: Initialize spi_device_id arrays using member names

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

iio: resolver: ad2s1210: notify trigger and clear state on fault read error

2026-05-16T18:25:17+00:00

ad2s1210_trigger_handler() walks several scan-mask branches and uses "goto error_ret" to land on the iio_trigger_notify_done() teardown at the bottom of the function for every I/O error -- except the MOD_CONFIG fault-register read, which uses a bare "return ret": if (st->fixed_mode == MOD_CONFIG) { unsigned int reg_val; ret = regmap_read(st->regmap, AD2S1210_REG_FAULT, ®_val); if (ret < 0) return ret; ... } Two problems on that path: - the handler returns a negative errno where the prototype expects an irqreturn_t (IRQ_HANDLED / IRQ_NONE), so the caller in the IIO core sees a value outside the enum; - iio_trigger_notify_done() is skipped, leaving the trigger busy-flag set. A single transient SPI/regmap error on the fault read then wedges the trigger so subsequent samples are dropped until the consumer is detached. Convert the error path to "goto error_ret" so the failure path goes through the same notify_done() teardown as every other error in the handler.

iio: Remove single use of macro definition for driver name

2025-06-09T06:45:36+00:00

There is really no reason for having the driver name as a macro definition if it is only used once (often as `.name` in `struct device_driver`). It is also more readable this way. Remove these macro definitions and instead use the string literal directly.

iio: resolver: Use iio_push_to_buffers_with_ts() to provide length for runtime checks.

2025-05-21T13:20:26+00:00

This new function allows us to perform debug checks in the helper to ensure that the overrun does not occur. Use it in all the simple cases where either a static buffer or a structure is used in the drivers.

iio: normalize array sentinel style

2025-04-22T18:10:04+00:00

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.
