The patch seems to fix coding style but the surrounding code is not in qemu.git. Please send another revision with your full code changes. I also notice that the macro in the surrounding code will not work: you need to use backslash ('\') so the preprocessor joins lines: #define foo(x) \ do { \ printf("foo %d\n", x); \ } while (0) If you forget the backslashes there will be compilation errors.

To prevent bitrot of the format string of the debug statement, files with conditional debug statements should ensure that printf is compiled always, and enclosed within if(0) statements and not in #ifdef.
