tty: serial/samsung: fix modular build
There are a few bugs in the samsung serial driver when built as a loadable module, which makes the console code unavailable, as well as giving no access to the 'printascii' early debug function. This adds the appropriate compile time conditionals. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
