Date: Sun, 6 Feb 2022 17:07:13 +0100 From: Heiner Kallweit <hkallweit1@...il.com> To: Jakub Kicinski <kuba@...nel.org>, David Miller <davem@...emloft.net>, Realtek linux nic maintainers <nic_swsd@...ltek.com> Cc: "netdev@...r.kernel.org" <netdev@...r.kernel.org> Subject: [PATCH net-next] r8169: factor out redundant RTL8168d PHY config functionality to rtl8168d_1_common() rtl8168d_2_hw_phy_config() shares quite some functionality with rtl8168d_1_hw_phy_config(), so let's factor out the common part to a new function rtl8168d_1_common(). In addition improve the code a little.
