tty: max3100: remove unused variable rts and remove unused assignment
Variable rts is being assigned but it is never read, hence it can be removed. The assignment to param_new to zero is redundant as it is being updates a few statements later, so remove this redundant assignment. Cleans up two clang warnings: drivers/tty/serial/max3100.c:277:3: warning: Value stored to 'rts' is never read drivers/tty/serial/max3100.c:439:2: warning: Value stored to 'param_new' is never read Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
