can: grcan: grcan_probe(): remove extra of_node_get()
commit562fed945e
upstream. In grcan_probe(), of_find_node_by_path() has already increased the refcount. There is no need to call of_node_get() again, so remove it. Link: https://lore.kernel.org/all/20220619070257.4067022-1-windhl@126.com Fixes:1e93ed26ac
