Subject: [PATCH] rust: of: use safe zero initialization for struct of_device_id
Date: Sun, 11 Oct 2026 15:23:54 +0200	[thread overview]
Message-ID: <20261011132353.272824-2-blum@kernel.org> (raw)

Since bindings::of_device_id implements Zeroable, use pin_init::zeroed()
instead of core::mem::zeroed().
