Subject: tty: Make tty_paranoia_check() file scope
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=82b8f888e99c81c609710901d8defbc8eff13f79;p=linux-beck.git

tty: Make tty_paranoia_check() file scope

tty_paranoia_check() is only used within drivers/tty/tty_io.c;
remove extern declaration in header and limit symbol to file scope.
