[alsa-devel] [PATCH] ALSA: opl3: remove redundant pointer opl3

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Variable opl3 is being assigned but is never used hence it is
redundant and can be removed.

Cleans up several clang warnings:
warning: variable 'opl3' set but not used [-Wunused-but-set-variable]

Signed-off-by: Colin Ian King <colin.king at canonical.com>
