ASoC: soc-pcm.c: Make sure DAI parameters cleared if the DAI becomes inactive 
The commit 1da681e528 ("ASoC: soc-pcm.c: Clear DAIs parameters after
stream_active is updated") tries to make sure DAI parameters can be
cleared properly through moving the cleanup to the place where stream
active status is updated. However, it will cause the cleanup only
happening in soc_pcm_close().

Suppose a case: aplay -Dhw:0 44100.wav 48000.wav. The case calls
soc_pcm_open()->soc_pcm_hw_params()->soc_pcm_hw_free()->
soc_pcm_hw_params()->soc_pcm_hw_free()->soc_pcm_close() in order. The
parameters would be remained in the system even if the playback of
44100.wav is finished.

The case requires us clearing parameters in phase of soc_pcm_hw_free().
However, moving the DAI parameters cleanup back to soc_pcm_hw_free()
has the risk that DAIs parameters never be cleared if there're more
than one stream, see commit 1da681e528 ("ASoC: soc-pcm.c: Clear DAIs
parameters after stream_active is updated") for more details.

To meet all these requirements, in addition to do DAI parameters
cleanup in soc_pcm_hw_free(), also check it in soc_pcm_close() to make
sure DAI parameters cleared if the DAI becomes inactive.

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 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.
