Subject: tty: serial/samsung: fix modular build
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84f57d9e3685500a7447fc09a6891ce218869174;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
