From 39b4b06b8b20ae011373bae5f9552cce17c47f64 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Tue, 8 Dec 2015 00:40:57 +0300 Subject: [PATCH] sh_eth: factor out common code from MDIO bitbang methods sh_mm[cd]_ctrl() and sh_set_mdio() all look mostly the same -- factor out their common code and put it into sh_mdio_ctrl().
