 drivers/video/fbdev/aty/mach64_ct.c: In function ‘aty_init_pll_ct’:
 drivers/video/fbdev/aty/mach64_ct.c:405:46: warning: variable ‘vga_dsp_on_off’ set but not used [-Wunused-but-set-variable]
 drivers/video/fbdev/aty/mach64_ct.c:405:30: warning: variable ‘vga_dsp_config’ set but not used [-Wunused-but-set-variable]
 drivers/video/fbdev/aty/mach64_ct.c:405:18: warning: variable ‘dsp_on_off’ set but not used [-Wunused-but-set-variable]
