Subject: TTY: tty3270, free tty driver properly
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2312e4f3b2f17cac2cf257c759ad48eb80fdf230;p=linux-beck.git

TTY: tty3270, free tty driver properly

On module unload, in tty3270_exit, we forgot to free the tty driver.
Add there a call to put_tty_driver.
