Subject: [PATCH 13/24] crypto: atmel-aes: reduce latency of DMA completion
Date: Thu, 17 Dec 2015 17:48:44 +0100	[thread overview]
Message-ID: <a8f43f97c34da143330a883cac79ac5f83f5b859.1450366831.git.cyrille.pitchen@atmel.com> (raw)
In-Reply-To: <cover.1450366831.git.cyrille.pitchen@atmel.com>

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.
