Subject: tty: Remove unset_locked_termios() error message
X-Git-Tag: v4.14-rc1~4042^2~53
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f658dca95075e0b6823650968edad68538494ab8;p=platform%2Fkernel%2Flinux-rpi.git

tty: Remove unset_locked_termios() error message

With the refactor of 'locked' from parameter to local,
it's now obvious locked cannot be NULL. Remove entire conditional.
