While the CEC adapter is configuring, it is not possible to transmit a CEC message with the CEC_MSG_FL_RAW flag set as this is blocked at the ioctl level. Check if this flag is set, and if so, allow the message to be transmitted. This is useful for debugging if the display has no physical address (typically because the HPD is pulled low while in Standby).

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.
