From cec753f5dd103fcfef28c1d1c942395000abe15e Mon Sep 17 00:00:00 2001 From: Sebastian Hesselbarth Date: Wed, 29 May 2013 09:32:43 +0000 Subject: net: mv643xx_eth: use phy_disconnect instead of phy_detach Using a separated mdio bus driver with mvmdio, phy_detach on network device removal will not stop the phy and finally lead to NULL pointer dereference in mvmdio due to non-existent network device. Use phy_disconnect instead to properly stop phy device from accessing network device prior removal of the network device. Signed-off-by: Sebastian Hesselbarth Signed-off-by: David S.
