Subject: [PATCH 4/8] [media] coda: use gen_pool_dma_alloc() to allocate iram buffer
Date: Fri, 1 Nov 2013 19:36:02 +0800 [thread overview]
Message-ID: <a4cb5380b1eeb1c634cedfe05d2a7dee950742a4.1383303752.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.
