From 7598469a6184e1017a77ebe78b5b66c52a6afc1c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 11 May 2016 15:42:08 +0200 Subject: [PATCH] ata: dwc: add DMADEVICES dependency The dwc_460ex SATA driver has become available on non-powerpc architectures and may cause randconfig build errors when CONFIG_DMADEVICES is not set and SATA_DWC_OLD_DMA is enabled: warning: (SATA_DWC_OLD_DMA) selects DW_DMAC_CORE which has unmet direct dependencies (DMADEVICES) ERROR: "dw_dma_probe" [drivers/ata/sata_dwc_460ex.ko] undefined! ERROR: "dw_dma_remove" [drivers/ata/sata_dwc_460ex.ko] undefined! This adds an explcit Kconfig dependency to CONFIG_SATA_DWC so we cannot run into broken configurations. While it would also be possible to build the driver with both CONFIG_DMADEVICES and SATA_DWC_OLD_DMA disabled, that case is not useful because there is no fallback to PIO mode when the DMA engine is not usable.
