Subject[PATCH 4.10 26/63] amd-xgbe: Dont overwrite SFP PHY mod_absent settings
Date
4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Lendacky, Thomas" <Thomas.Lendacky@amd.com>


[ 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.
