Subject: [PATCH net-next 13/14] net: stmmac: simplify atds initialisation
Date: Fri, 27 Feb 2026 09:54:10 +0000 [thread overview]
Message-ID: <E1vvuXy-0000000Avnk-10Q8@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <aaFpZvuIzOLaNM0m@shell.armlinux.org.uk>
atds is boolean, and there is only one place that its value is changed.
Simplify this to a boolean assignment.
