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"

Remove .owner field if calls are used which set it automatically.
./drivers/gpu/drm/stm/lvds.c:1213:3-8: No need to set .owner here. The core will do it.

The Low-Voltage Differential Signaling (LVDS) Display Interface
Transmitter handles the LVDS protocol: it maps the pixels received from
the upstream Pixel-DMA LCD-TFT Display Controller (LTDC) onto the LVDS
PHY.
It is composed of three sub blocks:
* LVDS host: handles the LVDS protocol (FPD / OpenLDI) and maps
its input pixels onto the data lanes of the PHY
* LVDS PHY: parallelize the data and drives the LVDS data lanes
* LVDS wrapper: handles top-level settings
The LVDS controller driver supports the following high-level features:
* FDP-Link-I and OpenLDI (v0.95) protocols
* Single-Link or Dual-Link operation
* Single-Display or Double-Display (with the same content
duplicated on both)
* Flexible Bit-Mapping, including JEIDA and VESA
* RGB888 or RGB666 output
* Synchronous design, with one input pixel per clock cycle
