commite38e486d66upstream. The recent commit in HD-audio stream management for changing the stripe control seems causing a regression on some platforms. The stripe control is currently used only by HDMI codec, and applying the stripe mask unconditionally may lead to scratchy and static noises as seen on some MacBooks. For addressing the regression, this patch changes the stream management code to apply the stripe mask conditionally only when the codec driver requested.

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.
