Oswald Buddenhagen 4102ac2975 ALSA: emu10k1: fix+optimize E-MU stereo capture DSP code
Presumably, JDC added the seemingly superfluous indirection over the
temporary register because without it he'd get only zero readings.
However, switching the X and Y operands (or using EMU32 as the A
operand in the temporary load) works just fine. Presumably a DSP bug?

The original code was also actually buggy, though: both channels used
the left volume control.

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.
