media: nuvoton: Fix an error check in npcm_video_ece_init()

Browse source

commit c4b7779abc upstream.

When function of_find_device_by_node() fails, it returns NULL instead of
an error code. So the corresponding error check logic should be modified
to check whether the return value is NULL and set the error code to be
returned as -ENODEV.
