Often just folding together of the common if (cond) printf; abort|igt_skip|igt_fail; pattern. But in a few cases I've ripped out more since the igt macros will already print the condition and errno. A few tests where more work (like ripping out return codes en masse) is needed left as-is. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
