From: "Mark A. Greer" Date: Tue, 18 Dec 2012 20:35:20 -0700 Subject: [PATCH] crypto: omap-sham - Convert to dma_request_slave_channel_compat() Use the dma_request_slave_channel_compat() call instead of the dma_request_channel() call to request a DMA channel. This allows the omap-sham driver use different DMA engines. CC: Dmitry Kasatkin Signed-off-by: Mark A.
