Subject: [PATCH 2/3] usb: storage: realtek_cr: Simplify residue calculation in rts51x_bulk_transport()
Date: Wed, 13 Aug 2025 12:12:49 +0200 [thread overview]
Message-ID: <20250813101249.158270-4-thorsten.blum@linux.dev> (raw)
In-Reply-To: <20250813101249.158270-2-thorsten.blum@linux.dev>
Simplify the calculation of 'residue' in rts51x_bulk_transport() and
avoid unnecessarily reassigning 'residue' to itself.
