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 ...

zorro: make match function take a const pointer

2024-07-10T08:25:54+00:00

In commit d69d80484598 ("driver core: have match() callback in struct bus_type take a const *"), the match callback for busses was changed to take a const pointer to struct device_driver. Unfortunately I missed fixing up the zorro code, and was only noticed after-the-fact by the kernel test robot. Resolve this issue by properly changing the zorro_bus_match() function.

zorro: Use helpers from ioport.h

2024-04-29T14:45:53+00:00

We can use the DEFINE_RES_MEM_NAMED() macro and resource_contains() helper instead of reimplementing them in the code. No functional change intended.

zorro: Make zorro_bus_type const

2024-02-19T10:10:55+00:00

Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the zorro_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

driver core: make struct bus_type.uevent() take a const *

2023-01-27T12:45:52+00:00

The uevent() callback in struct bus_type should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.

zorro: Drop useless (and hardly used) .driver member in struct zorro_dev

2021-08-05T12:37:04+00:00

The only actual use is to check in zorro_device_probe() that the device isn't already bound. The driver core already ensures this however so the check can go away which allows to drop the then assigned-only member from struct zorro_dev. If the value was indeed needed somewhere it can always be calculated by to_zorro_driver(z->dev.driver) .

zorro: Simplify remove callback

2021-08-05T12:37:04+00:00

The driver core only calls a remove callback when the device was successfully bound (aka probed) before. So dev->driver is never NULL. (And even if it was NULL, to_zorro_driver(NULL) isn't ...)
