dmaengine: SF_PDMA depends on HAS_IOMEM
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. Mends this build error: s390-linux-ld: drivers/dma/sf-pdma/sf-pdma.o: in function `sf_pdma_probe': sf-pdma.c:(.text+0x1668): undefined reference to `devm_ioremap_resource' Fixes: 6973886ad58e ("dmaengine: sf-pdma: add platform DMA support for HiFive Unleashed A00") Signed-off-by: Randy Dunlap <[email protected]> Reported-by: kernel test robot <[email protected]> Cc: Green Wan <[email protected]> Cc: Vinod Koul <[email protected]> Cc: [email protected] Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Vinod Koul <[email protected]>
