Date: Wed, 12 Oct 2011 09:38:35 +0900 From: Tomoya MORINAGA <tomoya-linux@....lapis-semi.com> To: Dan Williams <dan.j.williams@...el.com>, Vinod Koul <vinod.koul@...el.com>, linux-kernel@...r.kernel.org Cc: qi.wang@...el.com, yong.y.wang@...el.com, joel.clark@...el.com, kok.howg.ewe@...el.com, Tomoya MORINAGA <tomoya-linux@....lapis-semi.com> Subject: [PATCH 2/2 v2] pch_dma: Reduce wasting memory nr_channels is defined in "struct pch_dma". and struct pch_dma_chan is defined in "struct pch_dma". So, "sizeof(struct pch_dma_chan) * nr_channels" is unnecessary.
