[PATCH] PCI: mediatek: Fix refcount leak in mtk_pcie_subsys_powerup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.

Fixes: 87e8657ba99c ("PCI: mediatek: Add new method to get shared pcie-cfg base address")
