From ef403bcaf16b704b772cf33cc2871fb8693d3bb3 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 23 Apr 2015 15:09:07 -0300 Subject: [PATCH] [media] Input: TOUCHSCREEN_SUR40 should depend on HAS_DMA If NO_DMA=y: warning: (TOUCHSCREEN_SUR40 && VIDEO_TW68 && VIDEO_CX23885 && VIDEO_CX25821 && VIDEO_CX88 && VIDEO_SAA7134) selects VIDEOBUF2_DMA_SG which has unmet direct dependencies (MEDIA_SUPPORT && HAS_DMA) ERROR: "dma_unmap_sg" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined!

TOUCHSCREEN_SUR40 selects VIDEOBUF2_DMA_SG, which bypasses its dependency on HAS_DMA. Make TOUCHSCREEN_SUR40 depend on HAS_DMA to fix this.
