Thanks Nathan.
Andrew explained to me that this warning helps find bugs when
developing the complicated (some would say crazy) set of macros that
this pinctrl driver uses. It would be good to have this warning
available in clang. Do we have a clang issue opened for that?

Hi Joel,
I just opened https://github.com/ClangBuiltLinux/linux/issues/293.
I searched the LLVM issue tracker and haven't see any reference of this.
I can file an issue but if you are a little more familiar with this
warning, you are welcome to do it instead.
Thanks for the quick response,
Nathan
