media: atomisp: fix querycap initialization logic
Some recent changes at V4L2 core changed the way querycap is handled.
Due to that, this warning is generated:
WARNING: CPU: 1 PID: 503 at drivers/media/v4l2-core/v4l2-dev.c:885 __video_register_device+0x93e/0x1120 [videodev]
as introduced by this commit:
commit 3c1350501c21db8e3b1a38d9e97db29694305c3b
Author: Hans Verkuil <hverkuil-cisco@xs4all.nl>
Date: Tue Jul 23 04:21:25 2019 -0400
media: v4l2-dev/ioctl: require non-zero device_caps, verify sane querycap results
Now that all V4L2 drivers set device_caps in struct video_device, we can add
a check for this to ensure all future drivers fill this in.
The fix is simple: we just need to initialize dev_caps before
registering the V4L2 dev.
While here, solve other problems at VIDIOC_QUERYCAP ioctl.
