Subject: [PATCH v8 1/8] crypto: caam - allocate RNG instantiation descriptor with GFP_DMA
Date: Mon, 16 Mar 2020 08:00:40 -0700	[thread overview]
Message-ID: <20200316150047.30828-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20200316150047.30828-1-andrew.smirnov@gmail.com>

Be consistent with the rest of the codebase and use GFP_DMA when
allocating memory for a CAAM JR descriptor.
