usb: gadget: f_uac1_legacy: remove broken string configfs attributes

2026-09-14T11:34:44+00:00

[ Upstream commit 590d74ec8f488e06b9f1c0f8f0941f45531f3a55 ] The UAC1_STR_ATTRIBUTE macro defines configfs show/store handlers for the fn_play, fn_cap, and fn_cntl string options. The store function contains an inverted null check on the kstrndup() return value. This means every write attempt returns -ENOMEM on success and dereferences a NULL pointer on allocation failure. The attributes have been broken and unused for many years. Remove the UAC1_STR_ATTRIBUTE macro and the three attributes it generated. The internal defaults (FILE_PCM_PLAYBACK, FILE_PCM_CAPTURE, FILE_CONTROL) set in f_audio_alloc_inst() are unaffected.

Pull documentation updates from Jonathan Corbet: "It has been a relatively busy cycle for docs, especially the build system: - The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of the millennium. Over the following 25 years, it accumulated a vast amount of cruft, all in a language few people want to deal with anymore. Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft in the hope of avoiding regressions. Now that we have a more reasonable code base, though, we can work on cleaning it up; many of the changes this time around are toward that end. - A reorganization of the ext4 docs into the usual TOC format. - Various Chinese translations and updates. - A new script from Mauro to help with docs-build testing. - A new document for linked lists - A sweep through MAINTAINERS fixing broken GitHub git:// repository links. ...and lots of fixes and updates" * tag 'docs-6.17' of git://git.lwn.net/linux: (147 commits) scripts: add origin commit identification based on specific patterns sphinx: kernel_abi: fix performance regression with O= Documentation: core-api: entry: Replace deprecated KVM entry/exit functions docs: fault-injection: drop reference to md-faulty docs: document linked lists scripts: kdoc: make it backward-compatible with Python 3.7 docs: kernel-doc: emit warnings for ancient versions of Python Documentation/rtla: Describe exit status Documentation/rtla: Add include common_appendix.rst docs: kernel: Clarify printk_ratelimit_burst reset behavior Documentation: ioctl-number: Don't repeat macro names Documentation: ioctl-number: Shorten macros table Documentation: ioctl-number: Correct full path to papr-physical-attestation.h Documentation: ioctl-number: Extend "Include File" column width Documentation: ioctl-number: Fix linuxppc-dev mailto link overlayfs.rst: fix typos docs: kdoc: emit a warning for ancient versions of Python docs: kdoc: clean up check_sections() docs: kdoc: directly access the always-there KdocItem fields docs: kdoc: straighten up dump_declaration() ...

Documentation: treewide: Replace remaining spinics links with lore

2025-06-21T20:20:51+00:00

Long before introduction of lore.kernel.org, people would link to LKML threads on third-party archives (here spinics.net), which in some cases can be unreliable (as these were outside of kernel.org control). Replace links to them with lore counterparts (if any).

Documentation: usb: gadget: Wrap remaining usage snippets in literal code block

2025-06-19T10:25:32+00:00

Several configfs usage snippets forget to be formatted as literal code blocks. These were outputted in htmldocs output as normal paragraph instead. In particular, snippet for custom string descriptors as added in 15a7cf8caabee4 ("usb: gadget: configfs: Support arbitrary string descriptors") is shown as single combined paragraph, rather than two command lines. Wrap them like the rest of snippets.

This is to correct the mistaken byte offset of the field bDeviceClass in OP_REP_IMPORT documentation. The previous field bcdDevice has length 2 and the offset for bDeviceClass should be 0x138 + 2 = 0x13A instead of 0x139. Offsets for subsequent fields are also affected and fixed in this patch.
