From 2437d5ea2191f3059246a1a7ac6fc4c8cc004dec Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Sat, 6 May 2023 19:16:28 +0800 Subject: dmaengine: make QCOM_HIDMA depend on HAS_IOMEM 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 QCOM_HIDMA depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset. -------------------------------------------------------- ld: drivers/dma/qcom/hidma.o: in function `hidma_probe': hidma.c:(.text+0x4b46): undefined reference to `devm_ioremap_resource' ld: hidma.c:(.text+0x4b9e): undefined reference to `devm_ioremap_resource' make[1]: *** [scripts/Makefile.vmlinux:35: vmlinux] Error 1 make: *** [Makefile:1264: vmlinux] Error 2 Signed-off-by: Baoquan He Reviewed-by: Niklas Schnelle Cc: Andy Gross Cc: Bjorn Andersson Cc: Konrad Dybcio Cc: Vinod Koul Cc: linux-arm-msm@vger.kernel.org Cc: dmaengine@vger.kernel.org Reviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20230506111628.712316-3-bhe@redhat.com Signed-off-by: Vinod Koul --- drivers/dma/qcom/Kconfig | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/dma') diff --git a/drivers/dma/qcom/Kconfig b/drivers/dma/qcom/Kconfig index 3f926a653bd8..ace75d7b835a 100644 --- a/drivers/dma/qcom/Kconfig +++ b/drivers/dma/qcom/Kconfig @@ -45,6 +45,7 @@ config QCOM_HIDMA_MGMT config QCOM_HIDMA tristate "Qualcomm Technologies HIDMA Channel support" + depends on HAS_IOMEM select DMA_ENGINE help Enable support for the Qualcomm Technologies HIDMA controller. -- cgit
