This is actually a semantic change, in that cpm2_pic_node always gets
assigned now, whereas previously it didn't if node == NULL. Are you
sure that is OK? If so, you need to add something to the patch
description explaining why it is OK.

It's ok to remove 'node' check because in real life cpm2_pic_init() never
gets called with node == NULL.
