Subject: [PATCH 2/9] ALSA: cs5535audio: remove redundant pointer 'dma'

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

Pointer 'dma' is being assigned but is never used hence it is
redundant and can be removed.

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