The last parameter of these axi_dac_(frequency|scale|phase)_set()
functions is supposed to be true for TONE_2 and false for TONE_1. The
bug is the last call where it passes "private - TONE_2". That
subtraction is going to be zero/false for TONE_2 and and -1/true for
TONE_1. Fix the bug, and re-write it as "private == TONE_2" so it's
more obvious what is happening.

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.
