Subject: [PATCH v5 1/4] crypto: caam - allocate RNG instantiation descriptor with GFP_DMA
Date: Tue, 3 Dec 2019 08:23:54 -0800 [thread overview]
Message-ID: <20191203162357.21942-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20191203162357.21942-1-andrew.smirnov@gmail.com>
Be consistent with the rest of the codebase and use GFP_DMA when
allocating memory for a CAAM JR descriptor.
