Subject: [PATCH net-next 1/4] net: mtk_eth_soc: tidy mtk_gmac0_rgmii_adjust()
Date: Tue, 07 Mar 2023 16:19:26 +0000	[thread overview]
Message-ID: <E1pZa2A-00DFfD-JI@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <ZAdj9qUXcHUsK7Gt@shell.armlinux.org.uk>

Get rid of the multiple tenary operators in mtk_gmac0_rgmii_adjust()
replacing them with a single if(), thus making the code easier to read.
