[ Upstream commit f9d0ecbf56f4b90745a6adc5b59281ad8f70ab54 ]
The results of non-blocking transmits were not correctly communicated
to userspace.
Specifically:
1) if a non-blocking transmit was canceled, then rx_status wasn't set to 0
as it should.
2) if the non-blocking transmit succeeded, but the corresponding reply
never arrived (aborted or timed out), then tx_status wasn't set to 0
as it should, and rx_status was hardcoded to ABORTED instead of the
actual reason, such as TIMEOUT. In addition, adap->ops->received() was
never called, so drivers that want to do message processing themselves
would not be informed of the failed reply.

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.
