[ Upstream commit 0cfbb589d67f16fa55b26ae02b69c31b52e344b1 ]
When CONFIG_HAS_IOMEM is not set/enabled, certain iomap() family functions [including ioremap(), devm_ioremap(), etc.] are not available. Drivers that use these functions should depend on HAS_IOMEM so that they do not cause build errors.
Rectifies these build errors: s390-linux-ld: drivers/dma/qcom/hidma_mgmt.o: in function `hidma_mgmt_probe': hidma_mgmt.c:(.text+0x780): undefined reference to `devm_ioremap_resource' s390-linux-ld: drivers/dma/qcom/hidma_mgmt.o: in function `hidma_mgmt_init': hidma_mgmt.c:(.init.text+0x126): undefined reference to `of_address_to_resource' s390-linux-ld: hidma_mgmt.c:(.init.text+0x16e): undefined reference to `of_address_to_resource'
