If the type is VFL_TYPE_GRABBER, then also check device_caps to see if the video device supports video and/or metadata and disable unneeded ioctls. Without this change, format ioctls for both video and metadata devices could be called on both device nodes. This is true for other ioctls as well, even if the device supports only video or metadata. Metadata devices act similar to VBI devices w.r.t. which ioctls should be enabled. This makes sense since VBI *is* metadata.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
