[05/23] tty: serial/samsung: fix modular build

Commit Message

Arnd Bergmann March 5, 2013, 5:42 p.m. UTC

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.
