With C=1:
drivers/soc/renesas/rmobile-sysc.c:330:33: sparse: sparse: incorrect type in argument 1 (different address spaces) @@ expected void *addr @@ got void [noderef] __iomem *[assigned] base @@ drivers/soc/renesas/rmobile-sysc.c:330:33: sparse: expected void *addr drivers/soc/renesas/rmobile-sysc.c:330:33: sparse: got void [noderef] __iomem *[assigned] base
Fix this by adding the missing __iomem annotation to iounmap().
