I use these commands and also find another waring:

../drivers/spi/spi-mt65xx.c:589:25: warning: incorrect type in argument
1 (different address spaces)
../drivers/spi/spi-mt65xx.c:589:25: expected void const *ptr

vi drivers/spi/spi-mt65xx.c +589

588         mdata->base = devm_ioremap_resource(&pdev->dev, res);
589         if (IS_ERR(mdata->base)) {
590                 ret = PTR_ERR(mdata->base);
591                 goto err_put_master;
592         }

should I also fix them?

That'd be great if you could!  It's not 100% essential though.
