From 5d9b709a1724f27fbb17add0e287134b7039e0aa Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 23 Apr 2015 15:09:06 -0300 Subject: [PATCH] [media] v4l: VIDEOBUF2_DMA_SG should depend on HAS_DMA If NO_DMA=y: ERROR: "dma_unmap_sg" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined! ERROR: "dma_map_sg" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined! ERROR: "dma_sync_sg_for_cpu" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined! VIDEOBUF2_DMA_SG cannot be enabled manually by the user, it's always selected automatically by drivers that need it. Several of those drivers already have an explicit dependency on HAS_DMA. Make VIDEOBUF2_DMA_SG depend on HAS_DMA. This makes it easier to find drivers that select VIDEOBUF2_DMA_SG without depending on HAS_DMA, as Kconfig will give a warning.
