You need some text in the Change log. Say why this change is needed,
etc.
Looking through other users of of_irq_get(), i don't see any disposing
of the mapping. It is not obvious you need to do this. The name does
not give any hint.
Maybe we should add an of_irq_put() which would clean up the mapping?
