Subject: [PATCH] ata: dwc: add DMADEVICES dependency
Date: Wed, 11 May 2016 14:44:16 +0200 [thread overview]
Message-ID: <1462970683-451525-1-git-send-email-arnd@arndb.de> (raw)
The dwc_460ex SATA driver has become available on non-powerpc architectures
and may cause randconfig build errors when CONFIG_DMADEVICES is not set:
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 so we can only build
configurations that build without warnings.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Fixes: 50b433753df6 ("ata: sata_dwc_460ex: use "dmas" DT property to find dma channel")
