Subject: [PATCH] gpu: nova-core: fsp: use KVec::zeroed() in recv_msg()
Date: Tue, 6 Oct 2026 08:54:35 +0200 [thread overview]
Message-ID: <20261006065437.58408-3-blum@kernel.org> (raw)
Use KVec::zeroed() to create the message buffer in recv_msg() instead of
creating an empty vector and resizing it.
