From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The final assignment to port is never read, hence it is redundant
and can be removed. Also move the declaration of port to a more
local scope. Cleans up clang warning:
drivers/tty/serial/serial_core.c:1498:2: warning: Value stored
to 'port' is never read
