Zero the result code stored in a field of the scratch 0 register before issuing a generic EE command. This just guarantees that the value we read later was actually written as a result of the command. Also add the definitions of two more possible result codes that can be returned when issuing flow control enable or disable commands: INCORRECT_CHANNEL_STATE: - channel must be in started state INCORRECT_DIRECTION - flow control is only valid for TX channels Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

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.
