| Subject: [PATCH] drivers/of/of_mdio.c:fix of_mdiobus_register() |
| |
| commit 209c65b61d94344522c41a83cd6ce51aac5fd0a4 upstream. |
| |
| When registers a phy_device successful, should terminate the loop |
| or the phy_device would be registered in other addr. If there are |
| multiple PHYs without reg properties, it will go wrong. |
