Subject: mxser: remove tty->driver_data NULL check
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2fb19b957805e8d6b981cf339caecd7cb6a3893a;p=linux.git

mxser: remove tty->driver_data NULL check

Noone sets tty->driver_data to NULL in the driver, so there is no point
to check that in mxser_close(). Remove the check.
