I don't agree with it as a static analysis dev...What I mean is if it's a macro that returns -ENODEV or a function that returns -ENODEV, they should both be treated the same. The other warnings this check prints are quite clever.
I think this is what gcc tries to do, and it should work normally, but it
fails when using ccache. I know I had cases like that, not entirely sure
if this is one of them. Maybe it just means I should give up on using
ccache in preprocessor mode.
