Subject: linux-next: build failure after merge of the slave-dma tree

Hi Vinod,

After merging the slave-dma tree, today's linux-next build (arm
multi_v7_defconfig build) failed like this:

drivers/video/fbdev/Kconfig:5:error: recursive dependency detected!
For a resolution refer to Documentation/kbuild/kconfig-language.txt
subsection "Kconfig recursive dependency limitations"
drivers/video/fbdev/Kconfig:5:  symbol FB is selected by DRM_KMS_FB_HELPER

drivers/gpu/drm/virtio/Kconfig:1:       symbol DRM_VIRTIO_GPU depends on VIRTIO
drivers/virtio/Kconfig:1:       symbol VIRTIO is selected by REMOTEPROC

USB HIDBP Keyboard (simple Boot) support (USB_KBD) [N/m/y/?] (NEW) aborted!

Console input/output is redirected. Run 'make oldconfig' to update configuration.

/home/sfr/next/next/scripts/kconfig/Makefile:37: recipe for target 'silentoldconfig' failed

Probably caused by commits

  73f19dcade3d ("remoteproc: st_slim_rproc: add a slimcore rproc driver")
  e0cbdfc766bf ("dmaengine: st_fdma: Add STMicroelectronics FDMA engine driver support")
  a490790f8df3 ("ARM: multi_v7_defconfig: Enable STi and simple-card drivers.")

I have used the slave-dma tree from next-20160915 for today.
