My main focus is on the regmap-irq interface you are trying to add - why would a user of this interface want to do this as a separate step (which would require changing all the existing users...)? We're providing an interface to get the virq mapped to a particular interrupt in the device, it's not obvious that that is an allocation and it certainly wasn't the intention (this code predates us using domains). > So fix need to go in the irq_domain_remove() to unamp before actually > destroying the irq domain? That's one option, but you could also do this at the regmap-irq level.
