Takashi Iwai 112e3f5ac5 ALSA: hdsp: Make the firmware loading ioctl a bit more readable
The firmware loading ioctl that is implemented for hdsp hwdep device
takes the reference of the address pointer, hence the current code is
rather confusing.  Also, due to the recent change in uapi header,
sparse also complains about the cast.

This patch tries to improve the readability by converting the
straightforward copy_from_user of the whole struct (which contains
only the pointer).

Fixes: d63e63d421 ("ALSA: hdsp: Make uapi/hdsp.h compilable again")

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.
