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' Fixes: 67a2003e0607 ("dmaengine: add Qualcomm Technologies HIDMA channel driver") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kernel test robot <lkp@intel.com> Cc: Sinan Kaya <okaya@codeaurora.org> Cc: Vinod Koul <vkoul@kernel.org> Cc: dmaengine@vger.kernel.org --- drivers/dma/qcom/Kconfig | 1 + 1 file changed, 1 insertion(+)
