Yes, you're correct. The issue was already there in the code and I was
attempting to fix it. When I made the change I figured using only
regmap_irq_get_virq() was the way to go, but seems like I chose the wrong
option. Will make the changes (remove regmap_irq_get_virq()), test on both DT
and non-DT platforms, and then will re-submit the patches.
