Merge tag 'media/v4.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media fixes from Mauro Carvalho Chehab:
"Two regression fixes:
- a regression when handling VIDIOC_CROPCAP at the media core;
- a regression at adv7604 that was ignoring pad number in subdev ops"
* tag 'media/v4.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
[media] adv7604: Don't ignore pad number in subdev DV timings pad operations
[media] v4l2-ioctl: fix stupid mistake in cropcap condition
