The SWR2 Soundwire instance has 1 output and 4 input ports, so for the
headset recording (via the WCD9385 codec and the TX macro codec) we want
to use the next DAI, not the first one (see qcom,dout-ports and
qcom,din-ports for soundwire@6d30000 node).
Original code was copied from other devices like SM8450 and SM8550. On
the SM8450 this was a correct setting, however on the SM8550 this worked
probably only by coincidence, because the DTS defined no output ports on
SWR2 Soundwire.
This is a necessary fix for proper audio recording via analogue
microphones connected to WCD9385 codec (e.g. headset AMIC2).

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.
