[PATCH] MIPS: CPC: Fix refcount leak in mips_cpc_default_phys_base

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

 



of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
