Looks like I had Werror disabled and therefore just missed them. Sorry for that. Cheers, Andre'

While looking through the samsung tty driver, I've spotted a few things that can be simplified by removing unused function arguments and by avoiding some duplicated variables and casting. There are no functional changes here.
