2025-06-27docs: kdoc: split the processing of the two remaining inline statesJonathan Corbet1-19/+18
Now that "inline_*" are just ordinary parser states, split them into two separate functions, getting rid of some nested conditional logic. The original process_inline() would simply ignore lines that didn't match any of the regexes (those lacking the initial " * " marker). I have preserved that behavior, but we should perhaps emit a warning instead. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2025-06-27docs: kdoc: remove the inline states-within-a-stateJonathan Corbet1-30/+13
The processing of inline kerneldoc comments is a state like the rest, but it was implemented as a set of separate substates. Just remove the substate logic and make the inline states normal ones like the rest. INLINE_ERROR was never actually used for anything, so just take it out. No changes to the generated output.

2025-06-26checkpatch: check for comment explaining rgmii(|-rxid|-txid) PHY modesMatthias Schiffer1-0/+12
Historically, the RGMII PHY modes specified in Device Trees have been used inconsistently, often referring to the usage of delays on the PHY side rather than describing the board; many drivers still implement this incorrectly. Require a comment in Devices Trees using these modes (usually mentioning that the delay is realized on the PCB), so we can avoid adding more incorrect uses (or will at least notice which drivers still need to be fixed).

2025-06-25scripts: test_doc_build.py: make the script smarterMauro Carvalho Chehab1-49/+105
Most of the time, testing the full range of supported Sphinx version is a waste of time and resources. Instead, the best is to focus at the versions that are actually shipped by major distros. For it to work properly, we need to adjust the requirements for them to start from first patch for each distro after the minimal supported one. The requirements were re-adjusted to avoid build breakages related to version incompatibilities. Such builds were tested with: ./scripts/test_doc_build.py -m -a "SPHINXOPTS=-j8" "SPHINXDIRS=networking netlink/specs" --full Change the logic to pick by default only such versions, adding another parameter to do a comprehensive test.

The regex in the BODY_WITH_BLANK_LINE case was looking for lines starting with " * ", where exactly one space was allowed before the following text. There are many kerneldoc comments where the authors have put multiple spaces instead, leading to mis-formatting of the documentation. Specifically, in this case, the description portion is associated with the last of the parameters. Allow multiple spaces in this context. See, for example, synchronize_hardirq() and how its documentation is formatted before and after the change.

2025-06-24kconfig: lxdialog: fix 'space' to (de)select optionsYann E. MORIN1-1/+1
In case a menu has comment without letters/numbers (eg. characters matching the regexp '^[^[:alpha:][:digit:]]+$', for example - or *), hitting space will cycle through those comments, rather than selecting/deselecting the currently-highlighted option. This is the behaviour of hitting any letter/digit: jump to the next option which prompt starts with that letter. The only letters that do not behave as such are 'y' 'm' and 'n'. Prompts that start with one of those three letters are instead matched on the first letter that is not 'y', 'm' or 'n'. Fix that by treating 'space' as we treat y/m/n, ie. as an action key, not as shortcut to jump to prompt. Signed-off-by: Yann E.

As we always iterate through the entire die_map when expanding type strings, recursively processing referenced types in type_expand_child() is not actually necessary. Furthermore, the type_string kABI rule added in commit c9083467f7b9 ("gendwarfksyms: Add a kABI rule to override type strings") can fail to override type strings for structures due to a missing kabi_get_type_string() check in this function.

2025-06-07genksyms: Fix enum consts from a reference affecting new valuesPetr Pavlu1-7/+20
Enumeration constants read from a symbol reference file can incorrectly affect new enumeration constants parsed from an actual input file. Example: $ cat test.c enum { E_A, E_B, E_MAX }; struct bar { int mem[E_MAX]; }; int foo(struct bar *a) {} __GENKSYMS_EXPORT_SYMBOL(foo); $ cat test.c | ./scripts/genksyms/genksyms -T test.0.symtypes #SYMVER foo 0x070d854d $ cat test.0.symtypes E#E_MAX 2 s#bar struct bar { int mem [ E#E_MAX ] ; } foo int foo ( s#bar * ) $ cat test.c | ./scripts/genksyms/genksyms -T test.1.symtypes -r test.0.symtypes <stdin>:4: warning: foo: modversion changed because of changes in enum constant E_MAX #SYMVER foo 0x9c9dfd81 $ cat test.1.symtypes E#E_MAX ( 2 ) + 3 s#bar struct bar { int mem [ E#E_MAX ] ; } foo int foo ( s#bar * ) The __add_symbol() function includes logic to handle the incrementation of enumeration values, but this code is also invoked when reading a reference file. As a result, the variables last_enum_expr and enum_counter might be incorrectly set after reading the reference file, which later affects parsing of the actual input. Fix the problem by splitting the logic for the incrementation of enumeration values into a separate function process_enum() and call it from __add_symbol() only when processing non-reference data.

Overall, a lot of individual changes, but nothing major, just the normal constant forward progress of new device support and cleanups to existing subsystems. Highlights in here are: - Large IIO driver updates and additions and device tree changes - Android binder bugfixes and logfile fixes - mhi driver updates - comedi driver updates - counter driver updates and additions - coresight driver updates and additions - echo driver removal as there are no in-kernel users of it - nvmem driver updates - spmi driver updates - new amd-sbi driver "subsystem" and drivers added - rust miscdriver binding documentation fix - other small driver fixes and updates (uio, w1, acrn, hpet, xillybus, cardreader drivers, fastrpc and others) All of these have been in linux-next for quite a while with no reported problems" * tag 'char-misc-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (390 commits) binder: fix yet another UAF in binder_devices counter: microchip-tcb-capture: Add watch validation support dt-bindings: iio: adc: Add ROHM BD79100G iio: adc: add support for Nuvoton NCT7201 dt-bindings: iio: adc: add NCT7201 ADCs iio: chemical: Add driver for SEN0322 dt-bindings: trivial-devices: Document SEN0322 iio: adc: ad7768-1: reorganize driver headers iio: bmp280: zero-init buffer iio: ssp_sensors: optimalize -> optimize HID: sensor-hub: Fix typo and improve documentation iio: admv1013: replace redundant ternary operator with just len iio: chemical: mhz19b: Fix error code in probe() iio: adc: at91-sama5d2: use IIO_DECLARE_BUFFER_WITH_TS iio: accel: sca3300: use IIO_DECLARE_BUFFER_WITH_TS iio: adc: ad7380: use IIO_DECLARE_DMA_BUFFER_WITH_TS iio: adc: ad4695: rename AD4695_MAX_VIN_CHANNELS iio: adc: ad4695: use IIO_DECLARE_DMA_BUFFER_WITH_TS iio: introduce IIO_DECLARE_BUFFER_WITH_TS macros iio: make IIO_DMA_MINALIGN minimum of 8 bytes ...
