I'm not seeing this error. rtasd.c compilkes fine, but I am hitting another
error later in the build that keeps it from finishing.
arch/powerpc/platforms/52xx/mpc52xx_pic.c: In function ‘mpc52xx_irqhost_map’:
arch/powerpc/platforms/52xx/mpc52xx_pic.c:343: error: ‘irqchip’ may be used
uninitialized in this function
