Takashi Iwai 82420bd4e1 ALSA: hda/hdmi: Fix breakage at probing nvhdmi-mcp driver
After restructuring and splitting the HDMI codec driver code, each
HDMI codec driver contains the own build_controls and build_pcms ops.
A copy-n-paste error put the wrong entries for nvhdmi-mcp driver; both
build_controls and build_pcms are swapped.  Unfortunately both
callbacks have the very same form, and the compiler didn't complain
it, either.  This resulted in a NULL dereference because the PCM
instance hasn't been initialized at calling the build_controls
callback.

Fix it by passing the proper entries.

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 reStructuredText 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.
