Laurent Pinchart eec8125021 media: mc: Fix MUST_CONNECT handling for pads with no links 
Commit b3decc5ce7 ("media: mc: Expand MUST_CONNECT flag to always
require an enabled link") expanded the meaning of the MUST_CONNECT flag
to require an enabled link in all cases. To do so, the link exploration
code was expanded to cover unconnected pads, in order to reject those
that have the MUST_CONNECT flag set. The implementation was however
incorrect, ignoring unconnected pads instead of ignoring connected pads.
Fix it.

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 reStructuredText 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.
