Subject: [PATCH 3.18 09/38] ata: SATA_MV should depend on HAS_DMA

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <geert@...ux-m68k.org>


[ Upstream commit 62989cebd367a1aae1e009e1a5b1ec046a4c8fdc ]

If NO_DMA=y:

    ERROR: "dma_pool_alloc" [drivers/ata/sata_mv.ko] undefined!
    ERROR: "dmam_pool_create" [drivers/ata/sata_mv.ko] undefined!
    ERROR: "dma_pool_free" [drivers/ata/sata_mv.ko] undefined!

Add a dependency on HAS_DMA to fix this.
