This makes things simpler. There's no reason not to just embed the struct snd_dmaengine_dai_dma_data in struct sspa_priv and do away with an unnecessary kmalloc(). While at that, we can initialize the snd_dmaengine_dai_dma_data structures earlier. Let's also stop offsetting the source/destination of the DMA transfer by phys_base. Firstly, it's never set and is always zero. Secondly, the hardware actually ignores it, at least on a MMP2 and MMP3.

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.
