Subject: [PATCH REF 23/24] gpu: nova-core: replace ARef<Device> with &'a Device in SysmemFlush
Date: Tue, 28 Apr 2026 00:11:21 +0200	[thread overview]
Message-ID: <20260427221155.2144848-24-dakr@kernel.org> (raw)
In-Reply-To: <20260427221155.2144848-1-dakr@kernel.org>

Now that SysmemFlush is lifetime-parameterized, the ARef<Device> is
unnecessary -- a plain &'a Device reference suffices.
