the new and old interface."

This is completely bogus.

#1) The changelog does not match the patch at all

#2) This driver relies on the assumption that it sits behind an eoi
    capable interrupt line. If the implementation of the underlying
    chip changes from eoi to irq_eoi then this driver has to follow
    that change and not add a total bogosity.

Remove the sillyness and retrieve the interrupt data from irq_desc
directly. No need to got through circles to look it up.
