This patch converts the ASoC dmaenging driver code to use the new unified PCM copy callback. It's a straightforward conversion from *_user() to *_iter() variants. The process callback is still using the direct pointer as of now, but it'll be converted in the next patch. Note that copy_from/to_iter() returns the copied bytes, hence the error condition is adjusted accordingly.

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.
