Description
In the Linux kernel, the following vulnerability has been resolved:
irqchip/realtek-rtl: Fix refcount leak in map_interrupts
of_find_node_by_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
This function doesn't call of_node_put() in error path.
Call of_node_put() directly after of_property_read_u32() to cover
both normal path and error path.
