[PATCH 3/9] ALSA: emu10k1: remove redundant variable attn

From: Colin King
Date: Wed Aug 01 2018 - 06:47:55 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable attn is being assigned but is never used hence it is
redundant and can be removed.

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