This function always return '0' and no callers use the return value. So make it a void function. This eliminates the following coccicheck warning: ./drivers/usb/typec/tcpm/tcpm.c:778:5-8: Unneeded variable: "ret". Return "0" on line 794 Reported-by: Abaci Robot <abaci@linux.alibaba.com> Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> --- drivers/usb/typec/tcpm/tcpm.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-)
