Subject: [PATCH v2 4/6] rust: io: remove legacy relaxed accessors of Mmio
Date: Fri, 06 Feb 2026 15:00:18 +0900 [thread overview]
Message-ID: <20260206-io-v2-4-71dea20a06e6@nvidia.com> (raw)
In-Reply-To: <20260206-io-v2-0-71dea20a06e6@nvidia.com>
The relaxed access functionality is now provided by the `RelaxedMmio`
wrapper type, and we don't have any user of the legacy methods left.
Remove them.
