Message-Id: <1356813800-4705-1-git-send-email-ahemaily@gmail.com> Date: Sat, 29 Dec 2012 22:43:20 +0200 From: ahemaily@...il.com To: tony@...mide.com Cc: linux@....linux.org.uk, linux-arm-kernel@...ts.infradead.org, linux-omap@...r.kernel.org, linux-kernel@...r.kernel.org, ahemaily <ahemaily@...il.com> Subject: [PATCH 1/1] arm :omap :DMA: fix a bug on reserving the omap SDMA channels From: ahemaily <ahemaily@...il.com> The variable dma_lch_count used for comparison (omap_dma_reserve_channels <= dma_lch_count) before it initialized to the value from omap_dma_dev_attr : d->lch_count. I change the place of dma_lch_count initialization to be before the comparison.
