Subject: [PATCH v2 2/7] gpu: nova-core: vbios: remove unneeded u8 conversions
Date: Mon, 27 Oct 2025 21:54:42 +0900	[thread overview]
Message-ID: <20251027-nova-as-v2-2-a26bd1d067a4@nvidia.com> (raw)
In-Reply-To: <20251027-nova-as-v2-0-a26bd1d067a4@nvidia.com>

These variables were read from the u8 array `data` and converted to a
`usize`, before being converted back to a `u8`. Just re-read them from
the source to avoid using `as`.

Acked-by: Danilo Krummrich <dakr@kernel.org>
