Subject: [PATCH 4/7] rust: faux: impl AsRef<Device<Bound>> for Registration
Date: Fri, 30 May 2025 16:24:17 +0200	[thread overview]
Message-ID: <20250530142447.166524-5-dakr@kernel.org> (raw)
In-Reply-To: <20250530142447.166524-1-dakr@kernel.org>

The device contained in a faux::Registration is always bound, hence
consider this in the registrations's AsRef implementation.
