Hi all,

After merging the v4l-dvb tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/staging/media/imx/imx7-media-csi.c: In function 'imx7_csi_set_fmt':

Caused by commit

  05f634040c0d ("media: staging/imx7: add imx7 CSI subdev driver")

interacting with the earlier commit

  5964cbd86922 ("media: imx: Set capture compose rectangle in capture_device_set_format")

I have used the v4l-dvb tree from next-20190218 for today.
