It is possible for one HDMI connector to have multiple CEC adapters. The typical real-world scenario is that where one adapter is used when the device is in standby, and one that's better/smarter when the device is powered up. The cec-notifier changes were made with that in mind, but I missed that in order to support this you need to tell cec_notifier_cec_adap_unregister() which adapter you are unregistering from the notifier. Add this additional argument. It is currently unused, but once all drivers use this, the CEC core will be adapted for these use-cases.

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.
