From 17ae1c650c1ecf8dc8e16d54b0f68a345965f43f Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 3 Nov 2016 18:40:19 +0100 Subject: [PATCH] phy: fix device reference leaks Make sure to drop the reference taken by bus_find_device_by_name() before returning from phy_connect() and phy_attach(). Note that both function still take a reference to the phy device through phy_attach_direct().
