From 880dec12a25890e8f5626f04c58d38003f1a5585 Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Sat, 21 Jun 2025 21:43:28 +0200 Subject: rust: device: add drvdata accessors Implement generic accessors for the private data of a driver bound to a device. Those accessors should be used by bus abstractions from their corresponding core callbacks, such as probe(), remove(), etc. Implementing them for device::CoreInternal guarantees that driver's can't interfere with the logic implemented by the bus abstraction.
