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

../drivers/spi/spi-mt65xx.c:590:36: warning: incorrect type in argument
1 (different address spaces)
../drivers/spi/spi-mt65xx.c:590:36: expected void const *ptr
../drivers/spi/spi-mt65xx.c:590:36: got void [noderef] <asn:2>*base
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?
