Subject: TTY: tty3270, free tty driver properly
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2312e4f3b2f17cac2cf257c759ad48eb80fdf230;p=openwrt%2Fstaging%2Fblogic.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.
