The function samsung_dsim_parse_dt() calls of_graph_get_endpoint_by_regs() to get the endpoint device node, but fails to call of_node_put() to release the reference when the function returns. This results in a device node reference leak.

Fix this by adding the missing of_node_put() call before returning from the function.

Found via static analysis and code review.
