Merge tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH: "Here is the big set of driver core changes for 6.11-rc1. Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory. We aren't there yet, but are getting closer. - minor devres cleanups and fixes found by code inspection - arch_topology minor changes - other minor driver core cleanups All of these have been in linux-next for a very long time with no reported problems" * tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (55 commits) ARM: sa1100: make match function take a const pointer sysfs/cpu: Make crash_hotplug attribute world-readable dio: Have dio_bus_match() callback take a const * zorro: make match function take a const pointer driver core: module: make module_[add|remove]_driver take a const * driver core: make driver_find_device() take a const * driver core: make driver_[create|remove]_file take a const * firmware_loader: fix soundness issue in `request_internal` firmware_loader: annotate doctests as `no_run` devres: Correct code style for functions that return a pointer type devres: Initialize an uninitialized struct member devres: Fix memory leakage caused by driver API devm_free_percpu() devres: Fix devm_krealloc() wasting memory driver core: platform: Switch to use kmemdup_array() driver core: have match() callback in struct bus_type take a const * MAINTAINERS: add Rust device abstractions to DRIVER CORE device: rust: improve safety comments MAINTAINERS: add Danilo as FIRMWARE LOADER maintainer MAINTAINERS: add Rust FW abstractions to FIRMWARE LOADER firmware: rust: improve safety comments ...

HID: bpf: prevent the same struct_ops to be attached more than once

2024-07-24T16:27:21Z

If the struct_ops is already attached, we should bail out or we will end up in various locks and pointer issues while unregistering. Link: https://patch.msgid.link/20240723-fix-6-11-bpf-v1-3-b9d770346784@kernel.org Signed-off-by: Benjamin Tissoires

HID: amd_sfh: Move sensor discovery before HID device initialization

2024-07-23T17:09:38Z

Sensors discovery is independent of HID device initialization. If sensor discovery fails after HID initialization, then the HID device needs to be deinitialized. Therefore, sensors discovery should be moved before HID device initialization.

HID: wacom: more appropriate tool type categorization

2024-07-18T06:13:28Z

Recent eraser and pen tools are able to be distinguished by looking at its least significant nibble. This modification applies it to wacom_intuos_get_tool_type function and reduces its code lines.

HID: wacom: Modify pen IDs

2024-07-18T06:13:17Z

The pen ID, 0x80842, was not the correct ID for wacom driver to treat. The ID was corrected to 0x8842. Also, 0x4200 was not the expected ID used on any Wacom device. Therefore, 0x4200 was removed.
