Merge drm-misc-next-2025-08-21 into drm-rust-next
We need the DRM Rust changes that went into drm-misc before the
existence of the drm-rust tree in here as well.

Each deprecated function was deprecated in favor of its `multi` +variant (e.g. `mipi_dsi_generic_write()` and `mipi_dsi_generic_write_multi()`). +The `multi` variant of a function includes improved error handling and logic +which makes it more convenient to make several calls in a row, as most MIPI +drivers do. + +Drivers should be updated to use undeprecated functions.
