Subject: misc: open-dice: make OPEN_DICE depend on HAS_IOMEM
Date: Fri, 7 Jul 2023 21:58:47 +0800
On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common than
PCI devices. Hence it could have a fully functional s390 kernel with
CONFIG_PCI=n, then the relevant iomem mapping functions [including
ioremap(), devm_ioremap(), etc.] are not available.
Here let OPEN_DICE depend on HAS_IOMEM so that it won't be built to cause
below compiling error if PCI is unset:
------
ERROR: modpost: "devm_memremap" [drivers/misc/open-dice.ko] undefined!
ERROR: modpost: "devm_memunmap" [drivers/misc/open-dice.ko] undefined!
------
