Subject: [PATCH 2/9] ALSA: cs5535audio: remove redundant pointer 'dma'
Date: Wed,  1 Aug 2018 11:47:35 +0100	[thread overview]
Message-ID: <20180801104742.4328-3-colin.king@canonical.com> (raw)
In-Reply-To: <20180801104742.4328-1-colin.king@canonical.com>

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]

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