From: Russell King (Oracle) Date: Sun, 4 Feb 2024 12:13:02 +0000 (+0000) Subject: net: stmmac: remove eee_enabled/eee_active in stmmac_ethtool_op_get_eee() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0cb6daf549f99cc978fe4dd531d2426313fc08e4;p=linux.git net: stmmac: remove eee_enabled/eee_active in stmmac_ethtool_op_get_eee() stmmac_ethtool_op_get_eee() sets both eee_enabled and eee_active, and then goes on to call phylink_ethtool_get_eee(). phylink_ethtool_get_eee() will return -EOPNOTSUPP if there is no PHY present, otherwise calling phy_ethtool_get_eee() which in turn will call genphy_c45_ethtool_get_eee(). genphy_c45_ethtool_get_eee() will overwrite eee_enabled and eee_active with its own interpretation from the PHYs settings and negotiation result. Thus, when there is no PHY, stmmac_ethtool_op_get_eee() will fail with -EOPNOTSUPP, meaning eee_enabled and eee_active will not be returned to userspace. When there is a PHY, eee_enabled and eee_active will be overwritten by phylib, making the setting of these members in stmmac_ethtool_op_get_eee() entirely unnecessary. Remove this code, thus simplifying stmmac_ethtool_op_get_eee().
