Subject: [PATCH 07/14] ASoC: AMD: remove unused ‘dma_buffer’
Date: Thu,  8 Dec 2016 23:01:30 +0530	[thread overview]
Message-ID: <1481218297-17568-8-git-send-email-vinod.koul@intel.com> (raw)
In-Reply-To: <1481218297-17568-1-git-send-email-vinod.koul@intel.com>

In acp_dma_hw_params(), 'dma_buffer' is initialized, but not used. So
remove it.

sound/soc/amd/acp-pcm-dma.c: In function ‘acp_dma_hw_params’:
sound/soc/amd/acp-pcm-dma.c:673:25: warning: variable ‘dma_buffer’ set but not used [-Wunused-but-set-variable]
  struct snd_dma_buffer *dma_buffer;
