From 68ece1e2ce3a1cb0aac9f5af685cf18fa2fa31aa Mon Sep 17 00:00:00 2001 From: Yilin Chen <1479826151@qq.com> Date: Mon, 29 Dec 2025 00:52:34 +0800 Subject: [PATCH] rust: dma: remove incorrect safety documentation Removes a safety requirement that incorrectly states callers must ensure the device does not access memory while the returned slice is live, as this method doesn't return a slice.
