The media_create_pad_link() function doesn't correctly clear reject link type flags, nor does it set the DATA_LINK flag. It only works because the MEDIA_LNK_FL_DATA_LINK flag's value is 0. Fix it by returning an error if any link type flag is set. This doesn't introduce any regression, as nobody calls the media_create_pad_link() function with link type flags (easily checked by grepping for the flag in the source code, there are very few hits). Set the MEDIA_LNK_FL_DATA_LINK explicitly, which is a no-op that the compiler will optimize out, but is still useful to make the code more explicit and easier to understand.

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.
