No other functions use the return value of mxser_change_speed() and the return value is always 0 now. Make it return void. This fixes the following coccicheck warning: drivers/tty/mxser.c:645:5-8: Unneeded variable: "ret". Return "0" on line 650 Signed-off-by: Jason Yan <yanaijie@huawei.com> --- drivers/tty/mxser.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-)
