Jacky Huang 23efa74cfe tty: serial: ma35d1: Add a NULL check for of_node ...

commit acd09ac253 upstream.

The pdev->dev.of_node can be NULL if the "serial" node is absent.
Add a NULL check to return an error in such cases.

Fixes: 930cbf92db ("tty: serial: Add Nuvoton ma35d1 serial driver support")
