From 4174ecd78f6591a3d1ec04738ef7bc900a11f5ce Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Fri, 20 Dec 2013 01:41:12 +0300 Subject: sh_eth: do not reset PHY needlessly There's no need anymore to call phy_init_hw() to reset/resume the PHY from the driver, as the call chain in phylib already has reached it, and so reset/resumed the PHY (even resuming it twice). This duplicate reset is not only needless, it e.g. clears the PHY's interrupt enables just setup by phylib and so prevents the expected IRQs from the PHY.
