From b4b87a934c30fb91cbdd18ae028acdc361e1cf0f Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Tue, 8 Jan 2013 11:57:45 -0700 Subject: [PATCH] crypto: omap-aes - 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-aes driver use different DMA engines. CC: Dmitry Kasatkin Signed-off-by: Mark A.
