Colin Ian King d2f884612c ALSA: intel_hdmi: remove redundant variable cfg_val 
Variable cfg_val is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'cfg_val' set but not used [-Wunused-but-set-variable]

[ Background info about val_bit field from alsa-devel ML thread:
 tiwai: Actually this made me wonder what is the definition of val_bit.
	It seems always 1 in the current code after the commit
	964ca8083c. Pierre?
 pbossart: This val_bit is only there for debug/test, it should be set
	to one by default and has nothing to do with the lpcm_id.
	This variable was set even in patches before upstream
	submission and was never needed, I guess it must be a 9-yr
	old issue. Good catch!

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
