[PATCH 3/3] media: add V4L2_CAP_VDEV_CENTERED flag on vdev-centric drivers

Mauro Carvalho Chehab <[email protected]>
Newsgroups gmane.linux.kernel,gmane.linux.documentation,gmane.linux.drivers.video-input-infrastructure,gmane.comp.video.mjpeg.user,gmane.linux.kernel.renesas-soc,gmane.linux.usb.general
Message-ID <e0dfe1dc52d5c91bc75ffdb011a6714494409761.1503653839.git.mchehab@s-opensource.com> 
From: Mauro Carvalho Chehab <[email protected]>

Those devices are controlled via their V4L2 device. Add a
flag to indicate them as such.
