From a quick glance, this looks like yet another switch statement detection issue. I'll need to dig into it more (unless PeterZ, my shiny new co-maintainer, wants to take a look!)
Arnd, can you test this fix?
It took me a while, as I had lost the earlier reproducer and am currently testing linux-next/gcc-8 whereas the report was for v4.14/gcc-7.
I have finally found a new reproducer on linux-next/gcc-7 and confirmed that the warning is fixed now, both for gcc-7 and gcc-8.
Thanks for the fix!
