Subject: [PATCH 3/3] sh: dma: drop redundant size argument from strscpy in request_dma
Date: Mon, 20 Apr 2026 17:10:00 +0200 [thread overview]
Message-ID: <20260420150958.17072-7-thorsten.blum@linux.dev> (raw)
In-Reply-To: <20260420150958.17072-5-thorsten.blum@linux.dev>
The strscpy() size argument is optional if the destination buffer has a
fixed length. Use the two-argument version of strscpy() to copy 'dev_id'
to simplify the code.
