Subject: [PATCH 1/4] crypto: qce: Remove unneeded length check for scatterlist
Date: Tue, 30 Aug 2016 18:53:50 +0300	[thread overview]
Message-ID: <20160830155353.19500-2-voker57@gmail.com> (raw)
In-Reply-To: <20160830155353.19500-1-voker57@gmail.com>

From: Voker57 <voker57@gmail.com>

Current code avoids supplying scatterlist containing more data than used
to DMA. This leads to dropping data from scatterlists which would
leave some for next run.
