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
964ca8083c02. 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!
