Subject: [PATCH] drivers/video/aty/aty128fb.c: fix a warning pertaining to the
 aty128fb backlight variable

Fix the following warning in the aty128fb driver:

	drivers/video/aty/aty128fb.c:363:12: warning: 'backlight' defined but not used [-Wunused-variable]
	 static int backlight = 0;
		    ^

as the variable's value is only read if CONFIG_FB_ATY128_BACKLIGHT=y.  The
variable is also set if MODULE is unset[*].

[*] I wonder if the conditional wrapper around aty128fb_setup() should be
    using CONFIG_MODULE rather than MODULE.
