This function uses "One Function Cleans up Everything" style and that's basically impossible to do correctly. It's cleaner to write it with "clean up the most recent allocation". Patch fixes two isues: 1. If pdev->dcbaa = dma_alloc_coherent() fails then that leads to a NULL dereference inside the cdnsp_free_priv_device() function. 2. if cdnsp_alloc_priv_device() fails that leads to a double free because we free pdev->out_ctx.bytes in several places.

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.
