This patch introduces the ops table to each memory allocation type (SNDRV_DMA_TYPE_XXX) and abstract the handling for the better code management. Then we get separate the page allocation, release and other tasks for each type, especially for the SG buffer. Each buffer type has now callbacks in the struct snd_malloc_ops, and the common helper functions call those ops accordingly. The former inline code that is specific to SG-buffer is moved into the local sgbuf.c, and we can simplify the PCM code without details of memory handling.

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.
