4.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Lendacky, Thomas" <Thomas.Lendacky@xxxxxxx> [ Upstream commit 2697ea5a859b83ca49511dcfd98daf42584eb3cf ] If an SFP module is not present, xgbe_phy_sfp_phy_settings() should return after applying the default settings. Currently there is no return statement and the default settings are overwritten. Signed-off-by: Tom Lendacky <thomas.lendacky@xxxxxxx> Signed-off-by: David S.
