linux-toradex.git/rust/kernel/platform.rs, branch v6.14-rc6 Linux kernel for Apalis and Colibri modules rust: driver: address soundness issue in `RegistrationOps` 2025-01-07T10:31:45+00:00 Danilo Krummrich dakr@kernel.org 2025-01-03T16:46:03+00:00 e1a51c2bf4b3b20868a0e6e9520b11639bd363f1 The `RegistrationOps` trait holds some obligations to the caller and implementers. While being documented, the trait and the corresponding functions haven't been marked as unsafe. Hence, markt the trait and functions unsafe and add the corresponding safety comments. This patch does not include any fuctional changes.

The `RegistrationOps` trait holds some obligations to the caller and
implementers. While being documented, the trait and the corresponding
functions haven't been marked as unsafe.

Hence, markt the trait and functions unsafe and add the corresponding
safety comments.

This patch does not include any fuctional changes.

rust: platform: add basic platform device / driver abstractions 2024-12-20T16:21:05+00:00 Danilo Krummrich dakr@kernel.org 2024-12-19T17:04:16+00:00 683a63befc7385bf7f19ba30fc0b4b14961114c5 Implement the basic platform bus abstractions required to write a basic platform driver. This includes the following data structures: The `platform::Driver` trait represents the interface to the driver and provides `platform::Driver::probe` for the driver to implement. The `platform::Device` abstraction represents a `struct platform_device`. In order to provide the platform bus specific parts to a generic `driver::Registration` the `driver::RegistrationOps` trait is implemented by `platform::Adapter`.
