clang-tidy: altera-unroll-loops triggers on do {} while(false) #55436

Clang 14.0.0 I have a macro like this:

#define GET_ARG(...) do { get_arg_impl(__VA_ARGS__); } while(false)

clang-tidy suggests adding #pragma unroll even though that doesn't make sense because this is a single-iteration loop.

I have the same issue with the log macros in Zephyr. I'm surprised that this isn't a bigger issue for people. Is there a easy work around I'm missing?
