From 24799831d631239ff21ea1bf7feee832df48b81f Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Mon, 25 May 2026 22:20:58 +0200 Subject: rust: device: make Core and CoreInternal lifetime-parameterized Device references in probe callbacks are scoped to the callback, not the full binding duration. Add a lifetime parameter to Core and CoreInternal to accurately represent this in the type system.
