The first two patches fix issues relating to a CEC adapter
being disabled while a transmit is still in progress at the
hardware level. Unless the hardware is really disabled (i.e.
loses power) the transmit should just continue in order to
keep the hardware and framework state in sync, and to avoid
half-written messages on the bus.
The third patch fixes a mismatch between the API documentation
and the actual code w.r.t. reporting the results of a non-blocking
transmit.
The fourth patch adds helpers to make it easier for both drivers
and userspace to detect if the received message contains the
result of a non-blocking transmit.
The fifth patch makes the framework more robust, preventing ops
from being called when the device is already unregistered.
The sixth patch allows drivers to override the transmit timeout
value. And the last patch adds a new callback so drivers can take
actual when an adapter is fully configured (i.e. all logical addresses
are claimed) or unconfigured.

Hans
