Subject: [PATCH -next 2/4] ALSA: cs5535audio: Remove unused variable 'loop'

Reported by Clang [-Wunused-but-set-variable]

The variable 'loop' is introduced to print log but this commit
'commit a6477134db11 ("ALSA: asihpi: Update debug printing")'
had updated the printing and 'loop' was not printed.

Now the variable is not used by other code. Remove it for code cleaning.
