Subject: [PATCH 2/8] ARM: davinci: use gen_pool_dma_alloc() to sram.c
Date: Fri, 1 Nov 2013 19:36:00 +0800 [thread overview]
Message-ID: <9536ee2bbb1a8463ebb21068a750b61fa59900df.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.
