I copied you on the intro, but all the lists and all the maintainers was too long to cc. Being late in the cycle I didn't really intend for this to be for 4.2, but you can pick up this patch if you want to as it doesn't have any dependencies. If you don't, then I will submit the whole series for 4.3. > Acked-by: Bjorn Helgaas <bhelgaas@google.com> Thanks.

OK, why don't you just include this with the rest of the series, since I assume the whole series is related even if there's no actual dependency.

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also set IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.
