digi_acceleport: Drag the driver kicking and screaming into coding style
- The outbreak of acute bracketitus has been cured - The belief that brackets should have spaces everywhere likewise - Various other coding style tweaks - Use baud rates not Bfoo in the speed setup switch Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
