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"

Uwe writes:
Change struct platform_driver::remove() to return void
This is step b) of the plan outlined in commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value"), which completes the first major step of making the remove callback return no value. Up to now it returned an int which however was mostly ignored by the driver core and lured driver authors to believe there is some error handling.
Note that the Linux driver model assumes that removing a device cannot fail, so this isn't about being lazy and not implementing error handling in the core and so making .remove return void is the right thing to do.

drm/imagination: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Merge tag 'drm-next-2024-01-10' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "This contains two major new drivers:
- imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it
- xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake.
This also drops a bunch of the old UMS ioctls. It's been dead long enough.
amdgpu has a bunch of new color management code that is being used in the Steam Deck.
amdgpu also has a new ACPI WBRF interaction to help avoid radio interference.
Otherwise it's the usual lots of changes in lots of places.

drm/imagination: Implement firmware infrastructure and META FW support
The infrastructure includes parsing of the firmware image, initialising FW-side structures, handling the kernel and firmware command ringbuffers and starting & stopping the firmware processor.
This patch also adds the necessary support code for the META firmware processor.
Changes since v8: - Fix documentation for pvr_fwccb_process() - Corrected license identifiers
Changes since v6: - Add a minimum retry count to pvr_kccb_reserve_slot_sync()
Changes since v5: - Add workaround for BRN 71242 - Attempt to recover GPU on MMU flush command failure
Changes since v4: - Remove use of drm_gem_shmem_get_pages() - Remove interrupt resource name
Changes since v3: - Hard reset FW processor on watchdog timeout - Switch to threaded IRQ - Rework FW object creation/initialisation to aid hard reset - Added MODULE_FIRMWARE() - Use drm_dev_{enter,exit}

drm/imagination: Implement power management
Add power management to the driver, using runtime pm. The power off sequence depends on firmware commands which are not implemented in this patch.

drm/imagination: Implement power management
Add power management to the driver, using runtime pm. The power off sequence depends on firmware commands which are not implemented in this patch.
Changes since v8: - Corrected license identifiers
Changes since v5: - Use RUNTIME_PM_OPS() to declare PM callbacks - Add Kconfig dependency on CONFIG_PM
Changes since v4: - Suspend runtime PM before unplugging device on rmmod
Changes since v3: - Don't power device when calling pvr_device_gpu_fini() - Documentation for pvr_dev->lost has been improved - pvr_power_init() renamed to pvr_watchdog_init() - Use drm_dev_{enter,exit}
Changes since v2: - Use runtime PM - Implement watchdog
