The CEC specifications explicitly allows you to send poll messages and Image/Text View On messages to a TV, even when unconfigured (i.e. there is no hotplug signal detected). Some TVs will pull the HPD low when switching to another input, or when going into standby, but CEC should still be allowed to wake up such a display. Add support for sending messages with initiator 0xf (Unregistered) and destination 0 (TV) when no physical address is present. This also required another change: the CEC adapter has to stay enabled as long as 1) the CEC device is configured or 2) at least one filehandle is open for the CEC device.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
