However, RAID6_PQ is not defined in any Kconfig file, although it is used in several of them. :( Signed-off-by: Randy Dunlap <rdunlap@...radead.org> Cc: Anup Patel <anup.patel@...adcom.com> Cc: Vinod Koul <vinod.koul@...el.com> Cc: dmaengine@...r.kernel.org --- drivers/dma/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) --- linux-next-20170517.orig/drivers/dma/Kconfig +++ linux-next-20170517/drivers/dma/Kconfig @@ -101,7 +101,8 @@ config AXI_DMAC config BCM_SBA_RAID tristate "Broadcom SBA RAID engine support" - depends on (ARM64 && MAILBOX && RAID6_PQ) || COMPILE_TEST + depends on ARM64 || COMPILE_TEST + depends on MAILBOX && RAID6_PQ select DMA_ENGINE select DMA_ENGINE_RAID select ASYNC_TX_DISABLE_XOR_VAL_DMA
