Robin, Will,

Happy new year! Hope I can get some attention back on this patch.
Only difference from Robin's is it will do limited logging if spurious
interrupts still happen to occur on current or future CMN implementations.

In all honesty I'm not sure what you want me to say... now you've written the same patch that I already sent, but still with an incorrect commit message, and with some unrelated changes that aren't mentioned and have nothing to do with shutdown anyway. Please see:

https://www.kernel.org/doc/html/latest/process/submitting-patches.html#separate-your-changes

If you have a convincing argument that returning IRQ_NONE for unexpected spurious interrupts is a real and important concern, then please propose a general solution, because if it matters for arm-cmn then it matters for hundreds of other drivers too, by rough estimate:

$ git grep -l IRQ_NONE '*.c' | xargs git grep -L IRQF_SHARED | wc -l
834

Thanks,
Robin.
