2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Johan Hovold <[email protected]> commit eb833a9e0972f60beb4ab8104ad7ef6bf30f02fc upstream. Return EINVAL if new baud_base does not match the current one. The baud_base is device specific and can not be changed. This restores the old (pre-2005) behaviour which was changed due to a misunderstanding regarding this fact (see https://lkml.org/lkml/2005/1/20/84).
