如何修改串口节点映射关系

admin

ttyHS0--uart4
ttyHS1--uart5
想改为
ttyHS0--uart5
ttyHS1--uart4
在
kernel/msm-4.9/drivers/tty/tty_io.c:       
tty_line_name

f (!strncmp(driver->name, "ttyHS", 5) && (index + driver->name_base) == 0){
        i = sprintf(p, "%s%d", "ttyHS", 1);
}
else if (!strncmp(driver->name, "ttyHS", 5) && (index + driver->name_base) == 1){
        i = sprintf(p, "%s%d", "ttyHS", 0);
