Subject: tty: tty_ldisc: Remove the ret variable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=728648c7c8bb054023b9b9f367e349d5b0afafd8;p=linux.git

tty: tty_ldisc: Remove the ret variable

The int variable ret does not receive the return value in this function.
It should be removed and returned 0 directly.
