Subject: [PATCH 9/9] ALSA: intel_hdmi: remove redundant variable cfg_val

From: Colin Ian King <colin.king@...onical.com>

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]
