Srinivas Kandagatla 76867d0cb8 ASoC: qdsp6: q6routing: Conditionally reset FrontEnd Mixer
[ Upstream commit 861afeac7990587588d057b2c0b3222331c3da29 ]

Stream IDs are reused across multiple BackEnd mixers, do not reset the
stream mixers if they are not already set for that particular FrontEnd.

Ex:
amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1

would set the MultiMedia1 steam for SLIMBUS_0_RX, however doing below
command will reset previously setup MultiMedia1 stream, because both of them
are using MultiMedia1 PCM stream.

amixer cset iface=MIXER,name='SLIMBUS_2_RX Audio Mixer MultiMedia1' 0

reset the FrontEnd Mixers conditionally to fix this issue.

This is more noticeable in desktop setup, where in alsactl tries to restore
the alsa state and overwriting the previous mixer settings.

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.
