gah, sorry ... I have urge to crawl under a rock now for forgetting something 
this obvious ;-) .

Apart from the NULL check what more did I mess up? Should I send a fixup patch 
or do you want to do it?

go ahead if you like - this is the most current version of the driver and 
would be one patch less to worry about. It would after all come together 
during the merge window again.

And very basic boot of the SoC works even without the pinctrl driver, as the 
uart pins are of course set up by the bootloader.
