Set the swidget->private or dai->private to NULL after kfree in the error
handling in ipc_setup(). The private needs to be set NULL because if
ipc_setup() returns error, ipc_free() will be called later. ipc_free()
will judge the private is NULL or not to do the clearing.
For dai widget, dai->private is allocated and set in dai widget
ipc_setup(). So we need to check dai->private is NULL or not
in the ipc_free().

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.
