When building with "make W=1", we get a warning about an empty stub
function that does nothing but reassign its one of its arguments:

  drivers/video/fbdev/core/fbmon.c: In function 'fb_edid_to_monspecs':
  drivers/video/fbdev/core/fbmon.c:1497:67: error: parameter 'specs' set but not used [-Werror=unused-but-set-parameter]

We can simply make that function completely empty to avoid the warning.

This prevents a warning which everyone will see after "CFLAGS: add
-Wunused-but-set-parameter" is merged.
