Fundamentally the problem with arche_platform_wd_irq() is that the
indentation is too great.
"... if you need more than 3 levels of indentation, you’re screwed anyway,
and should fix your program."

I think a better solution would be to refactor the entire function. This
would make the logic of the function more clear as well IMHO.
Here is another tip to help:
https://www.kernel.org/doc/html/v4.10/process/coding-style.html#centralized-exiting-of-functions
Do you think you could try that?
