Moreover, the case of (uioinfo != NULL) && (pdev->dev.of_node != NULL) leads 
to equally ugly results too (freeing uoinfo when it is statically allocated).

I think, we should sort out these problems, but in another patch. It is 
totally unrelated to the problem solved by the original patch (memory leak 
caused by not freeing priv in case platform_get_irq() fails).
