[Linux-fbdev-devel] mode change policy

[James S. <jsi...@tr...>]

   Okay. I realize rounding up is also good for color depth changes.
Someone could pass in a color depth of 12. We can easily fudge this to
something that is supported. 

NOTE: If this is the case then most drivers are broken!!!!

They return a error instead. Also what is the policy for cards that can't
change modes. Right now most drivers return a -EINVAL if they can't change
a mode. Do we pass back the only mode the driver supports instead of
returning a error?
