After being asked to not depend on ARCH_QCOM* or similar, unsurprisingly compilation fails on UM as it has no I/O memory: drivers/built-in.o: In function `qcom_ebi2_probe': >> drivers/bus/qcom-ebi2.c:333: undefined reference to `devm_ioremap_resource' Fix this by letting the Kconfig atleast depend on HAS_IOMEM.
