Here and below, please change the "Warning" into "radeonsi" so
unsuspecting users will be more likely to understand what's going on.

Wait, why not use the std R600_ERR() macro that wraps fprintf() calls?

Because I didn't think of it. Looking through the source code, the
usage is pretty mixed. Is one preferred over the other?

Obviously, neither did I. As long as we're certain that the __FILE__ in the macro expands to something that includes radeon or radeonsi, I think both are fine, and we should probably go with the macro. But I don't care much either way.
