From 13c7f876c2aac59863f6d28bd72e98bc45be3c9a Mon Sep 17 00:00:00 2001 From: Cyrille Pitchen Date: Thu, 17 Dec 2015 17:48:44 +0100 Subject: [PATCH] crypto: atmel-aes - reduce latency of DMA completion atmel_aes_dma_callback() now directly calls the 'resume' callback instead of scheduling the done task, which in turn only calls the very same 'resume' callback.
