Hans Verkuil 8f4b5b0af7 media: cec-adap: return from cec_s_conn_info() if adap is invalid
Check if cec_s_conn_info is called with a valid cec adapter,
do nothing if it is invalid.

This makes it possible to call this function even if CEC support is
disabled in the kernel config.

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.
