This patch converts the SB Emu8000 driver code to use the new unified PCM copy callback. The conversion is a bit complicated because of many open code in emu8000_pcm.c. GET_VAL() and LOOP_WRITE() macros were rewritten / simplified with copy_from_iter(). As copy_from_iter() updates the internal offset value, we can drop the corresponding part, too.

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.
