Peter Ujfalusi 4a6261c2fd ASoC: SOF: Intel: hda-pcm: Place the constraint on period time instead of buffer time 
[ Upstream commit 45ad27d9a6 ]

Instead of constraining the ALSA buffer time to be double of the firmware
host buffer size, it is better to set it for the period time.
This will implicitly constrain the buffer time to a safe value
(num_periods is at least 2) and prohibits applications to set smaller
period size than what will be covered by the initial DMA burst.

Fixes: fe76d2e75a ("ASoC: SOF: Intel: hda-pcm: Use dsp_max_burst_size_in_ms to place constraint")

README 

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.
