From: Miaoqian Lin <linmq006@xxxxxxxxx> [ Upstream commit c56de483093d7ad0782327f95dda7da97bc4c315 ] of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. a6xx_gmu_init() passes the node to of_find_device_by_node() and of_dma_configure(), of_find_device_by_node() will takes its reference, of_dma_configure() doesn't need the node after usage. Add missing of_node_put() to avoid refcount leak.
