Description A refcount leak issue has been identified in the Linux kernel, specifically in the bcma mdio mii register function related to the bgmac Ethernet driver. The of get child by name() function returns a node pointer with an incremented refcount, which should be decremented using of node put() when no longer needed to prevent a refcount leak.
