From ea7e18289f44b0aa597026f16e7f4f6daa0f13ee Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Thu, 19 Dec 2024 18:04:04 +0100 Subject: rust: implement generic driver registration Implement the generic `Registration` type and the `RegistrationOps` trait. The `Registration` structure is the common type that represents a driver registration and is typically bound to the lifetime of a module. However, it doesn't implement actual calls to the kernel's driver core to register drivers itself. Instead the `RegistrationOps` trait is provided to subsystems, which have to implement `RegistrationOps::register` and `RegistrationOps::unregister`. Subsystems have to provide an implementation for both of those methods where the subsystem specific variants to register / unregister a driver have to implemented. For instance, the PCI subsystem would call __pci_register_driver() from `RegistrationOps::register` and pci_unregister_driver() from `DrvierOps::unregister`.
