Subject: tty: xtensa/iss, don't reassign to tty->port
X-Git-Tag: accepted/tizen/unified/20230118.172025~7413^2~157
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0894b13467a2771bd282e280cd5cc7049285c4e7;p=platform%2Fkernel%2Flinux-rpi.git

tty: xtensa/iss, don't reassign to tty->port

We already do tty_port_link_device in rs_init, so we don't need to
reassign a port to tty->port. It would be too late in tty::ops::open
anyway.
