When the compat output is missing (I don't think this is actually possible), or is disabled (and hence has no crtc), we would like to avoid dereferencing NULL pointers. This patch creates inline functions to extract the current compat output, crtc or associated RandR crtc structure, carefully checking for NULL pointers everywhere.
