Miaoqian Lin d9c8ad935d dmaengine: dw: dmamux: Fix device reference leak in rzn1_dmamux_route_allocate 
commit aa2e1e4563 upstream.

The reference taken by of_find_device_by_node()
must be released when not needed anymore.
Add missing put_device() call to fix device reference leaks.

Fixes: 134d9c52fc ("dmaengine: dw: dmamux: Introduce RZN1 DMA router support")
