headers: Remove swap.h from suspend.h

2026-08-25T19:12:26+00:00

Nothing in suspend.h needs swap.h. However, many files indirectly depend on some of swap.h's dependencies, so this is a large cross-subsystem patch. Stats: 42 are missing includes of interrupt.h (the question of why swap.h brings in interrupt.h remains unanswered). 10 missing includes of seq_file.h 5 missing includes of swap.h (obviously all files could have just added swap.h, but I preferred to bring in a more minimal inclusion set) 3 missing includes of highmem.h 2 missing includes of device.h 2 missing includes of string_choices.h 1 missing include of cacheflush.h 1 missing include of dma-direction.h 1 missing include of kthread.h 1 missing include of pagemap.h 1 missing include of string_helpers.h 1 missing include of writeback.h I tried to follow whatever conventions appeared to be in use for the various subsystems I touched; for example I added string_choices.h to drm_print.h instead of individually to each driver which used the functions declared there.

i2c: busses: drop redundant dev_err_probe() around irq helpers

2026-08-19T19:55:51+00:00

platform_get_irq(), devm_request_irq() and devm_request_threaded_irq() already print an error message via dev_err_probe() on failure, so wrapping their return value with another dev_err_probe() results in duplicate error output. Drop these redundant dev_err_probe() calls across i2c bus drivers and return the error code directly instead.

Pull i2c updates from Andi Shyti: "The main changes are support for shared SCL lines in i2c-gpio, a larger qcom-geni update covering tracing and transfer recovery and support for R-Car Gen5. The rest is mostly smaller driver, core and DT binding updates. Core and helpers: - support bus recovery with single-ended GPIOs - acpi: clean up resource handling - acpi: force ELAN1300 to 100 kHz - algo-bit: allow consumers to skip the optional bus test Drivers: - use generic bus frequency definitions in nomadik, octeon-core, microchip-corei2c, k1, davinci and pnx - i2c-gpio: support multiple buses sharing the same SCL line - qup: propagate clock enable failures - spacemit: configure SCL timing and clean up clock handling - amd-asf: guard against oversized firmware length qcom-geni: - add tracepoints for bus setup, interrupts and errors - use dedicated completion events for abort and reset - distinguish address and data NACK handling - cancel transfers before falling back to abort - simplify runtime PM and resource management - refactor resource and serial engine initialization DT bindings: - convert Altera bindings to DT schema - convert Axxia bindings to DT schema New support: - R-Car Gen5 and R-Car X5H - Axiado AX3005 - Qualcomm Nord SA8797P - Qualcomm SA8255p" * tag 'i2c-7.3-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux: (33 commits) i2c: core: support recovery for single-ended GPIOs i2c: rcar: add R-Car Gen5 support dt-bindings: i2c: rcar-i2c: Document R-Car X5H support i2c: i2c-gpio: Enhance driver for buses with shared SCL i2c: algo: bit: Allow to skip bit test i2c: qcom-geni: Add trace events for Qualcomm GENI I2C driver i2c: qcom-geni: trace: Add trace events for Qualcomm GENI I2C i2c: qup: Propagate clock enable failures i2c: qcom-geni: distinguish address-phase and data-phase NACK i2c: qcom-geni: use dedicated completions for abort and reset events i2c: qcom-geni: use cancel command before abort on transfer timeout dt-bindings: i2c: cdns: add Axiado AX3005 I2C variant i2c: qcom-geni: Use devm_pm_runtime_enable() for PM management dt-bindings: i2c: qcom,sa8255p-geni-i2c: Add compatible for Nord SA8797P i2c: nomadik: Use generic definitions for bus frequencies i2c: octeon-core: Use generic definitions for bus frequencies i2c: microchip-corei2c: Use generic definitions for bus frequencies i2c: k1: Use generic definitions for bus frequencies i2c: davinci: Use generic definitions for bus frequencies i2c: pnx: Use generic definitions for bus frequencies ...

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.

i2c: amd-asf: Validate firmware-reported length

2026-07-01T08:50:24+00:00

The firmware may sometimes return a length greater than the allocated buffer size, which can lead to out-of-bounds access and a kernel panic. Currently, the driver does not validate the length read from firmware. Add a check to ensure the firmware-reported length stays within the bounds of the data buffer.

i2c: amd-asf: Fix EOI register write to enable successive interrupts

2025-02-26T22:28:41+00:00

The commit b1f8921dfbaa ("i2c: amd-asf: Clear remote IRR bit to get successive interrupt") introduced a method to enable successive interrupts but inadvertently omitted the necessary write to the EOI register, resulting in a failure to receive successive interrupts. Fix this by adding the required write to the EOI register.

module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.
