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.
