Subject: [PATCH 8/8] ASoC: pxa: use gen_pool_dma_alloc() to allocate dma buffer
Date: Fri, 1 Nov 2013 19:36:06 +0800	[thread overview]
Message-ID: <290c4ed99f88c1d07544bf5f8f0c9a1d09395bed.1383303752.git.b42378@freescale.com> (raw)
In-Reply-To: <cover.1383303752.git.b42378@freescale.com>

Since gen_pool_dma_alloc() is introduced, we implement it to simplify code.
