Conflicts: drivers/net/usb/asix_common.c net/ipv4/inet_connection_sock.c net/switchdev/switchdev.c In the inet_connection_sock.c case the request socket hashing scheme is completely different in net-next. The other two conflicts were overlapping changes. Signed-off-by: David S. Miller

net: dsa: exit probe if no switch were found

2015-10-07T11:56:11+00:00

If no switch were found in dsa_setup_dst, return -ENODEV and exit the dsa_probe cleanly. Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller

net: dsa: switch to devm_ calls and remove kfree calls

2015-10-07T11:56:09+00:00

Now the kfree calls exists in the the remove functions, remove them in all places except the of_probe functions and replace allocation calls with their devm_ counterparts. Reviewed-by: Florian Fainelli Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller

net: dsa: complete dsa_switch_destroy

2015-10-07T11:56:08+00:00

When unbinding dsa, complete the dsa_switch_destroy to unregister the fixed link phy then cleanly unregister and destroy the net devices. Reviewed-by: Florian Fainelli Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller

net: dsa: add missing dsa_switch mdiobus remove

2015-10-07T11:56:07+00:00

To prevent memory leakage on unbinding, add missing mdiobus unregister and unallocation calls. Reviewed-by: Florian Fainelli Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller

net: dsa: add missing kfree on remove

2015-10-07T11:56:06+00:00

To prevent memory leakage on unbinding, add missing kfree calls. Includes minor cosmetic change to make patch clean. Signed-off-by: Neil Armstrong Signed-off-by: David S. Miller

net: dsa: better error reporting

2015-10-07T09:58:49+00:00

Add additional error reporting to the generic DSA code, so it's easier to debug when things go wrong. This was useful when initially bringing up 88e6176 on a new board. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Acked-by: Florian Fainelli Signed-off-by: David S. Miller

net: fix net_device refcounting

2015-09-25T06:04:53+00:00

of_find_net_device_by_node() uses class_find_device() internally to lookup the corresponding network device. class_find_device() returns a reference to the embedded struct device, with its refcount incremented. Add a comment to the definition in net/core/net-sysfs.c indicating the need to drop this refcount, and fix the DSA code to drop this refcount when the OF-generated platform data is cleaned up and freed. Also arrange for the ref to be dropped when handling errors. Signed-off-by: Russell King Signed-off-by: David S. Miller

net: dsa: fix of_mdio_find_bus() device refcount leak

2015-09-25T06:04:52+00:00

Current users of of_mdio_find_bus() leak a struct device refcount, as they fail to clean up the reference obtained inside class_find_device(). Fix the DSA code to properly refcount the returned MDIO bus by: 1. taking a reference on the struct device whenever we assign it to pd->chip[x].host_dev. 2. dropping the reference when we overwrite the existing reference. 3. dropping the reference when we free the data structure. 4. dropping the initial reference we obtained after setting up the platform data structure, or on failure. In step 2 above, where we obtain a new MDIO bus, there is no need to take a reference on it as we would only have to drop it immediately after assignment again, iow: put_device(cd->host_dev); /* drop original assignment ref */ cd->host_dev = get_device(&mdio_bus_switch->dev); /* get our ref */ put_device(&mdio_bus_switch->dev); /* drop of_mdio_find_bus ref */ Signed-off-by: Russell King Signed-off-by: David S.

net: dsa: Allow DSA and CPU ports to have a phy-mode property

2015-08-31T21:48:02+00:00

It can be useful for DSA and CPU ports to have a phy-mode property, in particular to specify RGMII delays. Parse the property and set it in the fixed-link phydev. Signed-off-by: Andrew Lunn Acked-by: Florian Fainelli Signed-off-by: David S. Miller
