break kconfig dependency loop
After adding virtio-gpu I get this funky kconfig dependency loop. scripts/kconfig/conf --oldconfig Kconfig drivers/video/fbdev/Kconfig:5:error: recursive dependency detected! drivers/video/fbdev/Kconfig:5: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:34: symbol DRM_KMS_FB_HELPER is selected by DRM_VIRTIO_GPU drivers/gpu/drm/virtio/Kconfig:1: symbol DRM_VIRTIO_GPU depends on VIRTIO drivers/virtio/Kconfig:1: symbol VIRTIO is selected by REMOTEPROC drivers/remoteproc/Kconfig:4: symbol REMOTEPROC is selected by OMAP_REMOTEPROC drivers/remoteproc/Kconfig:12: symbol OMAP_REMOTEPROC depends on OMAP_IOMMU drivers/iommu/Kconfig:141: symbol OMAP_IOMMU is selected by VIDEO_OMAP3 drivers/media/platform/Kconfig:96: symbol VIDEO_OMAP3 depends on VIDEO_V4L2 drivers/media/v4l2-core/Kconfig:6: symbol VIDEO_V4L2 depends on I2C drivers/i2c/Kconfig:7: symbol I2C is selected by FB_DDC drivers/video/fbdev/Kconfig:59: symbol FB_DDC is selected by FB_CYBER2000_DDC drivers/video/fbdev/Kconfig:374: symbol FB_CYBER2000_DDC depends on FB_CYBER2000 drivers/video/fbdev/Kconfig:362: symbol FB_CYBER2000 depends on FB Making VIDEO_OMAP3 depend on OMAP_IOMMU instead of selecting it breaks the loop, which looks like the best way to handle it to me. Updated OMAP_IOMMU help text accordingly. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
