From: Lendacky, Thomas Date: Thu, 10 Nov 2016 23:10:46 +0000 (-0600) Subject: net: phy: expose phy_aneg_done API for use by drivers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=372788f964c95a6fa0f677c43d6153c27896ef42;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git net: phy: expose phy_aneg_done API for use by drivers Make phy_aneg_done() available to drivers so that the result of the auto-negotiation initiated by phy_start_aneg() can be determined. Remove the local implementation of phy_aneg_done() from the Aeroflex driver and use the phy library version. Signed-off-by: Tom Lendacky Signed-off-by: David S.
